DaVinci SoC updates for v3.12

Browse Source 
-----------------------------
 
 This set of SoC updates contains changes to the
 way UART clock is handled to enabled DT-boot to
 obtain UART clock frequency instead of relying
 on DT-binding being supplied. Similarly handling
 of MDIO clock is fixed to make it easier to support
 MDIO in DT-boot. Finally there is patch to remove
 now unnecessary setting of wake-up capable flag for
 RTC.
