mainboard/google/zoombini: mrc cache

this enables the MRC recovery cache for zoombini & variants.

the Kconfig options are:

HAS_RECOVERY_MRC_CACHE
MRC_CLEAR_NORMAL_CACHE_ON_RECOVERY_RETRAIN

one note of caution:  early board builds will likely fail to boot with:

tlcl_extend: response is 0
tlcl_extend: response is 0
tlcl_lock_nv_write: response is 0
tlcl_lock_nv_write: response is 28b
Failed to lock rec hash space(1f)
Saving nvdata
hard_reset() called!

the fix is to boot into recovery once, then it's business as usual.

using servo, this can be done with:

dut-control power_state:rec
