Refactor GPIO programming to support UFS storage on the fatcat
platform.
- Add pad configurations for UFS in `fw_config.c`.
- Update `fw_config_configure_pre_mem_gpio()` and
`fw_config_gpio_padbased_override()` to include UFS support.
- Remove redundant UFS pad configuration from `gpio.c`.
TEST=Able to build and boot from UFS device on google/fatcat.
