On the GP EVM, the ambient light sensor is limited to 100KHz on the
I2C bus.

So use 100kHz for I2C on the GP EVM due to this limitation on the
ambient light sensor.

Adds pinmux and DT node for Micron (MT29F4G08AB) x8 NAND device present on
am437x-gp-evm board.
(1) As NAND Flash data lines are muxed with eMMC, Thus at a given time either
    eMMC or NAND can be enabled. Selection between eMMC and NAND is controlled:
    (a) By dynamically driving following GPIO pin from software
        SPI2_CS0(GPIO) == 0 NAND is selected (default)
        SPI2_CS0(GPIO) == 1 eMMC is selected
    (b) By statically using Jumper (J89) on the board

(2) As NAND device connnected to this board has page-size=4K and oob-size=224,
    So ROM code expects boot-loaders to be flashed in BCH16 ECC scheme for
    NAND boot.

The VTT regulator for DDR3 termination on the am437x-gp-evm is
controlled by a gpio. It is configured by the bootloader so here we
define an always-on, fixed voltage regulator to hold the gpio.

Do not reset GPIO5 at boot-up because GPIO5_7 is used
on AM437x GP-EVM to control VTT regulators on DDR3.
Without this some GP-EVM boards will fail to boot because
of DDR3 corruption.
