Javier Martinez Canillas 582841a4f6 rtc: mt6397: Remove plaform module alias
The driver uses the MODULE_ALIAS() macro to export a platform module alias
to allow the module to be autoloaded if the device is registered using the
legacy platform registration mechanism but the driver is always used by OF
only machines so the alias is not needed and should just be removed.

Javier Martinez Canillas 73798d5c41 rtc: Fix module autoload for OF platform drivers
These platform drivers have a OF device ID table but the OF module
alias information is not created so module autoloading won't work.

Wei-Ning Huang baeca4495f rtc: mt6397: enable wakeup before registering rtc device
rtc_sysfs_add_device checks if device can wakeup before creating the
wakealarm file in sysfs. Thus the driver must set wakeup capability
before registering the rtc device.

Alexandre Belloni 9393996761 rtc: mt6397: fix build on some 32bits platforms
On some !ARM 32bits platforms, the following compilation error happens
because of the division on a 64bits value in mtk_rtc_read_time():

drivers/built-in.o: In function `mtk_rtc_read_time':
rtc-mt6397.c:(.text+0x265d13f): undefined reference to `__divdi3'
rtc-mt6397.c:(.text+0x265d150): undefined reference to `__moddi3'

Use div_s64() as done in rtc_time64_to_tm() to solve that.
