[PATCH 0/3] Enable SCU standby support at core level

With SCU standby support, SCU CLK will be turned off when all processors
are in WFI mode.  And the clock will be turned on when any processor
leaves WFI mode.  This behavior should be preferable in terms of power
efficiency of system idle.

The patch series enables SCU standby support in SCU core function
scu_enable(), and then clean up the SCU standby enabling code at i.MX
platform level.
