Matthias Schiffer a038a3ff8c powerpc/6xx: set High BAT Enable flag on G2_LE cores 
MMU_FTR_USE_HIGH_BATS is set for G2_LE cores and derivatives like e300cX,
but the high BATs need to be enabled in HID2 to work. Add register
definitions and add the needed setup to __setup_cpu_603.

This fixes boot on CPUs like the MPC5200B with STRICT_KERNEL_RWX enabled
on systems where the flag has not been set by the bootloader already.

Fixes: e4d6654ebe ("powerpc/mm/32s: rework mmu_mapin_ram()")
