arch: remove frv port

The Fujitsu FRV kernel port has been around for a long time, but has not
seen regular updates in several years and instead was marked 'Orphaned'
in 2016 by long-time maintainer David Howells.

The SoC product line apparently is apparently still around in the form
of the Socionext Milbeaut image processor, but this one no longer uses
the FRV CPU cores.

This removes all FRV specific files from the kernel.

-		   =======================================
-		   FUJITSU FR-V LINUX KERNEL CONFIGURATION
-		   =======================================
-
-=====================
-CONFIGURATION OPTIONS
-=====================
-
-The most important setting is in the "MMU support options" tab (the first
-presented in the configuration tools available):
-
- (*) "Kernel Type"
-
-     This options allows selection of normal, MMU-requiring linux, and uClinux
-     (which doesn't require an MMU and doesn't have inter-process protection).
-
-There are a number of settings in the "Processor type and features" section of
-the kernel configuration that need to be considered.
-
- (*) "CPU"
-
-     The register and instruction sets at the core of the processor. This can
-     only be set to "FR40x/45x/55x" at the moment - but this permits usage of
-     the kernel with MB93091 CB10, CB11, CB30, CB41, CB60, CB70 and CB451
-     CPU boards, and with the MB93093 PDK board.
-
- (*) "System"
-
-     This option allows a choice of basic system. This governs the peripherals
-     that are expected to be available.
-
- (*) "Motherboard"
-
-     This specifies the type of motherboard being used, and the peripherals
-     upon it. Currently only "MB93090-MB00" can be set here.
-
- (*) "Default cache-write mode"
-
-     This controls the initial data cache write management mode. By default
-     Write-Through is selected, but Write-Back (Copy-Back) can also be
-     selected. This can be changed dynamically once the kernel is running (see
-     features.txt).
-
-There are some architecture specific configuration options in the "General
-Setup" section of the kernel configuration too:
-
- (*) "Reserve memory uncached for (PCI) DMA"
-
-     This requests that a uClinux kernel set aside some memory in an uncached
-     window for the use as consistent DMA memory (mainly for PCI). At least a
-     megabyte will be allocated in this way, possibly more. Any memory so
-     reserved will not be available for normal allocations.
-
- (*) "Kernel support for ELF-FDPIC binaries"
-
-     This enables the binary-format driver for the new FDPIC ELF binaries that
-     this platform normally uses. These binaries are totally relocatable -
-     their separate sections can relocated independently, allowing them to be
-     shared on uClinux where possible. This should normally be enabled.
-
- (*) "Kernel image protection"
-
-     This makes the protection register governing access to the core kernel
-     image prohibit access by userspace programs. This option is available on
-     uClinux only.
-
-There are also a number of settings in the "Kernel Hacking" section of the
-kernel configuration especially for debugging a kernel on this
-architecture. See the "gdbstub.txt" file for information about those.
-
-
-======================
-DEFAULT CONFIGURATIONS
-======================
-
-The kernel sources include a number of example default configurations:
-
- (*) defconfig-mb93091
-
-     Default configuration for the MB93091-VDK with both CPU board and
-     MB93090-MB00 motherboard running uClinux.
-
-
- (*) defconfig-mb93091-fb
-
-     Default configuration for the MB93091-VDK with CPU board,
-     MB93090-MB00 motherboard, and DAV board running uClinux.
-     Includes framebuffer driver.
-
-
- (*) defconfig-mb93093
-
-     Default configuration for the MB93093-PDK board running uClinux.
-
-
- (*) defconfig-cb70-standalone
-
-     Default configuration for the MB93091-VDK with only CB70 CPU board
-     running uClinux. This will use the CB70's DM9000 for network access.
-
-
- (*) defconfig-mmu
-
-     Default configuration for the MB93091-VDK with both CB451 CPU board and
-     MB93090-MB00 motherboard running MMU linux.
-
- (*) defconfig-mmu-audio
-
-     Default configuration for the MB93091-VDK with CB451 CPU board, DAV
-     board, and MB93090-MB00 motherboard running MMU linux. Includes
-     audio driver.
-
- (*) defconfig-mmu-fb
-
-     Default configuration for the MB93091-VDK with CB451 CPU board, DAV
-     board, and MB93090-MB00 motherboard running MMU linux. Includes
-     framebuffer driver.
-
- (*) defconfig-mmu-standalone
-
-     Default configuration for the MB93091-VDK with only CB451 CPU board
-     running MMU linux.
