[PATCH 3/3] RTC/nuc900: fix build warning

[Wan ZongShun <mcuos.com@gmail.com>]

Firstly,I am sorry for this patch, because I omit the warning
when I submit 'nuc900-rtc-change-the-waiting-for-device-ready-implement.patch'.
so I have to send a patch to fix it.

It is reported by Nuvoton test guys, thanks.
