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.
