Well spotted.
I have a mpc8321, hence e300c2.
MMU_FTR_USE_HIGH_BATS is set for G2-based cores (G2_LE, e300cX), but the
high BATs need to be enabled in HID2 to work. Add register definitions
and introduce a G2 variant of __setup_cpu_603.
This fixes boot on CPUs like the MPC5200B with STRICT_KERNEL_RWX enabled.
