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.

of this board support is simply to assist in the CC13xx architecture
development. Serious board development will occur later. Board
support is missing LED and button support.
2019-02-10: Figured out how to connect J-Link and began debug. First
failure is in tiva_configgpio() while trying to configure the console
UART pins. The failure is a hardfault apparently generated by:

2019-02-12: Now hard-faults in tiva_lowsetup() here:
109 regval = getreg32(TIVA_GPIO_DOE);
352 ctl = getreg32(TIVA_CONSOLE_BASE + TIVA_UART_CTL_OFFSET);
The GPIO base address and DOE register offset seem to be okay. Must
be some issue with powering up the GPIO? The TI code calls Power_init()
which has not yet be brought into NuttX. Could this be the issue?
Most likely UART0 clocking is not being enabled correctly.
