This series of patches fixes a hang seen when loading U-Boot from SPI
or NAND on Seaboard and Harmony due to a missing PLLX init. It also
corrects a UARTD bit error in clk_rst.h, and adds rudimentary GPIO
support so that the UART on Seaboard can be used by U-Boot (UARTD &
SPIFLASH are muxed, and the default POR setting is for SPI access, so
GPIO_PI3 has to be driven low to enable serial console I/O over UARTD).
Harmony has no SPIFLASH, so the issue doesn't exist there.

With these changes, I can write U-Boot to SPI on Seaboard and boot with
it to the U-Boot cmd prompt. This should also apply to loading from NAND
on Seaboard and Harmony - testing to follow.

Changes in V2:
	- Change 2nd patch's description to 'Add basic GPIO definitions'
	- Add more descriptive comment for CPCON use in init_pllx

  arm: Tegra2: Add missing PLLX init
  arm: Tegra2: GPIO: Add basic GPIO definitions
  arm: Tegra2: Move clk/mux init to board_early_init_f, add GPIO init
