mb/google/brya: Select USE_UNIFIED_AP_FIRMWARE_FOR_UFS_AND_NON_UFS

This patch selects USE_UNIFIED_AP_FIRMWARE_FOR_UFS_AND_NON_UFS for
Google/Trulo variant which intends to achieve a unified AP firmware
image across UFS and non-UFS skus.

Note: Enabling this config would introduce an additional warm reset
during the cold-reset scenarios due to the function disabling of the
UFS controller as results we are expecting ~300ms higher boot time
(which might not be user visible because `cbmem -t` can't include
impacted boot time due to in-between resets).

BUG=b:355384185
TEST=Able to enter S0ix on Trulo eMMC sku after disabling UFS
during boot path.

Able to grep below debug prints while booting the eMMC sku.

[INFO ]  FW_CONFIG value from CBI is 0x20000000
[INFO ]  Disabling UFS controllers
...
[INFO ]  fw_config match found: STORAGE=STORAGE_EMMC
