NAND uses wait pin only to indicate device readiness after
a block/page operation. It is not use to extend individual
read/write cycle and so read/write wait pin monitoring must
be disabled for NAND.

This patch also gets rid of the below warning when NAND is
accessed for the first time.

am437x-gp-evm uses a NAND chip with page size 4096 bytes
and spare area of 225 bytes per page.

For such a setup it is preferrable to use BCH16 ECC scheme over
BCH8. This also makes it compatible with ROM code ECC scheme so
we can boot with NAND after flashing from kernel.

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.

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.
