Bug fix: RTC alarm wake-up

Browse source 
Because of the S3C2410 bug (INT_SRCPND_RTC not set on alarm wake-up), the firmware need to check on power-on if an alarm is triggered by comparing the alarm date to the system date.
But, It failed because the firmware read a system date that is 1 second behind the alarm date, while the cpu was waked-up by an alarm.
This is because x49gp uses 2 different functions to read host system time in 2 key routines, leading to a 1 second gap when used consecutively.
This fix solved this issue.
