mb/google/brya/var/taniks: Run time probe for NVMe SSD and MMC
Taniks will use two PCIE port signals with one slot, one CLK and one
CLKREQ at next build. In order to accommodate this, probe statements
are added to the devicetree. This only affects NVME SSD and EMMC.
BUG=b:215040000
TEST=Build FSP with debug output enabled, and observe the correct root
ports being initialized depending on the FW_CONFIG values for BOOT_EMMC
and BOOT_NVME.
