On the XEA board (imx28) one needs in the SPL support for GPIO, MMC and SPI. Two last ones are necessary for booting the device. The GPIO support allows deciding which medium will be used. For example the GPIO DTS node (gpio@0 at imx28.dtsi) has pinctrl parent (pinctrl@80018000) for which we don't need driver asigned for correct operation. In the spl/dts/dt-platdata.c the gpio@0 has index 4 and its parent - pinctrl@80018000 has index 5. In the bind_drivers_pass() function (at drivers/core/lists.c) call to device_bind_by_name() for `fsl_imx23_pinctrl` returns -2, which is expected. With current setup - when the SPL_OF_PLATDATA_PARENT=y The gpio@0 node with index 4 is skipped as its parent with 5 is not yet bound. It cannot be as we don't need and provide the driver for it. As a result the gpio@0 is never bound and we end up with bricked board in the SPL stage. When CONFIG_SPL_OF_PLATDATA_PARENT is NOT set, all entries from spl/dts/dt-platdata.c are scanned in ascending index order, so gpio@0 is properly initialized. For `fsl_imx_pinctrl` we simply check 10 times if the driver for is available (which is not) and exit. As a result the GPIOs are initialized and can be used in early SPL stage.

The usage of the preboot feature is now controlled via a separate Kconfig option - namely CONFIG_USE_PREBOOT. It must be enabled for preboot code executing commands now defined in CONFIG_PREBOOT (also moved to the Kconfig). After defining both CONFIG_USE_PREBOOT and CONFIG_PREBOOT in imx28_xea_defconfig the define of CONFIG_PREBOOT shall be removed from xea.h as it is redundant.

On the imx287 pin GPMI_WRN (GPIO0_25) no PullUP is available that can be
enabled.
To get the same behavior for both boot select pins (i.e. GPIO0_2{35})
disable pull UPs on both.

SPI flash on this machine is located on bus 1, default to using bus 1
for SPI flash and stop aliasing it to bus 0.

- Fix GPIO hog flags on DHCOM boards
The GPIO hog flags are ignored by gpiolib-of.c now, set the flags to 0. Since GPIO_ACTIVE_HIGH is defined as 0, this change only increases the correctness of the DT.

The GPIO hog flags are ignored by gpiolib-of.c now, set the flags to 0. Due to a change in gpiolib-of.c, setting flags to GPIO_ACTIVE_LOW and using output-low DT property leads to the GPIO being set high instead.

- Fix I2C speed for Nokia RX51
It looks like that i2c bus lot of times timeout on some units. Prior
migration to CONFIG_DM_I2C i2c speed was set to CONFIG_SYS_OMAP24_I2C_SPEED
value which was 100000. Lower speed fixes timeout problems, so change speed
back to its previous value.
