OMAP4: L2X0: fine tune PL310 configuration
Align with TI Android 3.0 kernel on following setup:
- read/modify/write for AUX_CTRL register (reserved bits shall be
preserved)
- disable Instruction prefetch as it does not bring better performances
- setup Prefetch Offset (or Control) Register:
- disable double line fill to avoid ARM errata 732672
(potentially prevents data corruption)
- optimized prefetch offset value (considering no double line fetch)
This is a collection of changes brough up by following contributors:
Santosh Shilimkar <santosh.shilimkar@ti.com>
Colin Cross <ccross@android.com>
Konstantin Shlyakhovoy <x0155534@ti.com>
