This has been done in order to align the DT of U-Boot with the DT
of Linux. In Linux, a phandle from a '-gpio' DT property is linked
to the pinctrl driver, a single driver that handles both pinctrl
settings and offers GPIO API to callers. On the other hand,
U-Boot redirects such phandle to a corresponding UCLASS_GPIO
driver, because U-Boot offers two different types of drivers
in this case: UCLASS_PINCTRL which handles pin functions and
UCLASS_GPIO which handles gpio requests as a gpio provider.
Due to this, we have two drivers in Uboot, but the Devicetree
has a single node. Thus, just one of the drivers can be probed
for the DT node during platform initialization, before relocation.
Our previous solution in U-Boot was to have a different devicetree:
the gpio node has a subnode for the pinctrl driver, which
is not compliant with Linux ABI. Furthermore, our documentation
for this type of nodes mentions no such gpio compatible.
After this patch, we can no longer add nodes with a gpio
compatible in the DT. Thus, in order to link the pinctrl driver to
the gpio one, a hook to the bind method of the former in U-Boot has
been added and the GPIO related compatibles have been removed to
avoid conflict when compatibles are enumerated and bound to drivers
during platform start before relocation. The bind method will attach
the GPIO driver to the pinctrl DT node so that every phandle coming
from '-gpio' DT properties will be redirected to a valid driver
attached to the pinctrl DT node.

This patch makes sure that the Devicetree for the sama7
boards are aligned with the Devicetree from Linux. This
implies removing the GPIO compatible and replacing it
with the PINCTRL one, as well as unifying the SDMMC
pinctrl related subnodes under one single subnode.

Whenever the SD Card would be removed and then re-inserted while in the
U-Boot command line, the `SDBPWR` bit of the `SDMMC_PCR` register would
remain unset afterwards. In order for the bit to be set again after
re-insertion, register an additional `deferred_probe` method that the
DM would then transparently call. This method will call the generic
`sdhci_probe` which will, during its execution flow, set this bit to 1.

Verdin iMX8M Plus:
- loadaddr=0x48280000 allows for 128.5MB area for uncompressing (ie FIT
images, kernel_comp_addr_r, kernel_comp_size)
- fdt_addr_r = loadaddr + 127.5MB : allows for 127.5MB kernel
- scriptaddr = fdt_addr_r + 512KB : allows for 512KB fdt
- ramdisk_addr_r = scriptaddr + 512KB : allows for 512KB script
Memory layout taken from commit fd5c7173ad
("imx8m{m,n}_venice: update env memory layout") but moved loadaddr by an
additional 0.5MB to avoid "Moving Image from 0x48200000 to 0x48280000"

Commit 99c7cc58e1 ("ddr: imx: Add i.MX9 DDR controller driver")
contains an inobvious side-effect which renders all systems using
DRAM controller at 3732 MT/s unbootable. The change is located in
ddrphy_init_set_dfi_clk(), where the switch case statement entry
3732 changed to entry 3733, so any board with DDR calibration data
for 3732 MT/s operations needs to be updated to 3733 MT/s to match
the change.
Since there is currently only one such board, update the board instead
of handling both 3732 and 3733 options in the driver. It is likely the
NXP MX8MP RPA update will follow and use the later value too.
