mb/google/brya: fix MRC cache failure for hynix parts

Set the cs_pi_start_high_in_ect if the DUT is using one of the two
following Hynix parts: H54G56CYRBX247 and H54G46CYRBX267.  Failure to
set cs_pi_start_high_in_ect when using these parts will result in an
MRC cache failure and DUT will fail to boot.

BUG=b:292153199
TEST=`emerge-brya coreboot chromeos-bootimage`, flash and boot brya
variant to kernel.
