ARM: shmobile: kzm9g: Support Real Time Clock
KZM-A9-GT board has RTC device r2025d at I2C channel 0
with slave address 0x64.
This patch enables reading and writing hardware real time clock on
KZM-A9-GT board. Interrupt is not yet supported.
How to test this patch using user space command.
Read RTC
# hwclock -r
Copy system clock to RTC
# hwclock -w
Shutdown and power off the board, and wait a while, then power on again.
Check RTC still keeps correct date.
