MIPS: Loongson32: Fix config brokenness; select SYS_SUPPORTS_32BIT_KERNEL
Commit a96d68ba3b41 ("MIPS: Loongson32: clarify we don't support MIPS16 and merge configs") attempted to reduce duplication in Kconfig by consolidating some selects common to Loongson 1B & 1C CPUs under CPU_LOONGSON1. Unfortunately it clearly wasn't tested because by removing SYS_SUPPORTS_32BIT_KERNEL it prevented 32BIT from being enabled leading to all sorts of strange build errors from a kernel configured to build as neither 32 nor 64 bit. Both loongson1b_defconfig & loongson1c_defconfig failed to build due to this problem. Revert the cleanup portions of commit a96d68ba3b41 ("MIPS: Loongson32: clarify we don't support MIPS16 and merge configs"), keeping only its removal of the selection of SYS_SUPPORTS_MIPS16. Signed-off-by: Paul Burton <paul.burton@mips.com> Fixes: a96d68ba3b41 ("MIPS: Loongson32: clarify we don't support MIPS16 and merge configs")
