mb/google/poppy/variants/rammus: fix S0ix entering issue
As we don't use the MIPI camera on Rammus, disable SA Imaging Unit and
CIO2 devices to avoid the system failed to enter S0ix.
BUG=b:114502527
BRANCH=master
TEST=On DUT, echo freeze > /sys/power/state
1. check the S0ix status on EC console
2. check the value of /sys/kernel/debug/pmc_core/slp_s0_residency_usec
