meta-facebook: clemente: add 998-rtc-detection script

Add the 998-rtc-detection script to phosphor-static-norootfs-init
to dynamically detect and bind the correct RTC device driver during
the early boot stage (initramfs).

Since the Clemente platform might be populated with different RTC
components at the same I2C address (0x6f on bus 6), this script
reads the device ID from register 0x10 to identify the hardware:
- If 0x5c: Instantiates the NCT3018Y RTC driver.
- If 0x4e: Instantiates the PCF85053A RTC driver.
