The driver skips hardware initialization if it is already configured by
the earlier bootloader stage (BL30). Skip the initialization only if the
hardware is really initialized and enabled.

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.
This commit fixes XEA regression introduced with e41651fffd.

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.

TXC line is directly connected from the SoC to the KSZ9131 PHY. There
is a transient state on this signal, before configuring it to RGMII,
which leads to packet transmit being blocked.
Keeping a pull-up when muxing this pin as function A (G0_TXCK) fixes
the issue.
