mb/google/brox: Configure ISH device based on FW_CONFIG
ISH Firmware name needs to be configured only when full sensing
capabilities are enabled through ISH_ENABLE FW_CONFIG. Similarly DMA
property needs to be added only when UFS is enabled through STORAGE_UFS
FW_CONFIG. Hence configure the ISH device at run-time based on
FW_CONFIG.
BUG=b:319164720
TEST=Build Brox BIOS image and boot to OS.
