MIPS: Malta: Add back RTC support

Browse Source 
With the conversion of MIPS to RTC_LIB the old RTC driver CONFIG_RTC became
unselectable.  Fix by setting up a platform device.  Also enable
RTC_CLASS so system time gets set from RTC on kernel initialization.

[Ralf: Original patch by Tiejun; polished nice and shiny by me]
