sm8450-common: Fix battery and USB OTG detection
* In cape (msm-5.10) pmic driver now lies in adsp [1], so
adsp firmware must to be loaded along with qti battery/
charger kernel module, in order to get battery and usb
power_supply up & running
* With this, we dont need to set usb mode to peripheral
explicitly either
* The GKI kernel for 5.10 explicitly disabled
FW_LOADER_USER_HELPER_FALLBACK, and the right way to enable it is to
echo 1 to the /proc/sys/kernel/firmware_config/force_sysfs_fallback,
so do this before writing to adsp sysfs node.
