Squashed commit of the following:

arch/arm/src/tiva/cc13xx/cc13xx_prcm.c:  Fix reverse bit modification:  Set the bit to enabled clocking, clear the bit to dissable clocking.
    arch/arm/src/tiva/cc13xx/cc13xx_enablepwr.c:  Use correct index for determining if this the SERIAL or PERIPH power domain.
