The PCA9450 reset configuration can now be performed by the PCA9450 PMIC
driver itself, remove the hard-coded variant from board code and let the
PMIC driver perform this task using one-liner:
```
$ sed -i '/set WDOG_B_CFG to cold reset/,+2 d' $(git grep -l PCA9450_RESET_CTRL.*0xA1 board/)
```
Venice and i.MX93 EVK required slight manual fix up.

The current implementation of spl_board_init() USB boot handling is
not correct, the MX8MM BootROM v1 does not support SDP load when
re-entered from U-Boot SPL, it is up to U-Boot to perform the next
stage load using its own internal CI gadget driver and SDP protocol
implementation. Drop the spl_board_init() to let SPL continue with
normal load in case the SDP support is enabled.

Instead of duplicating code implemented by i.MX8M version of arch_misc_init()
in every board, enable CONFIG_ARCH_MISC_INIT and call arch_misc_init() from
spl_board_init(). This removes the duplication. No functional change.

Synchronise device tree with linux v5.19-rc5.
Please note that this also means that instead of the previous "generic"
U-Boot specific carrier board agnostic device tree we are now using the
regular one for the Verdin Development (carrier) board (e.g.
imx8mm-verdin-wifi-dev.dtb rather than the previous imx8mm-verdin.dtb).
Please further note that the PMIC node name got changed from a pmic
label to pmic@25 which required adjustment in resp. board SPL file
board/toradex/verdin-imx8mm/spl.c.

Move the preloader_console_init() call after spl_early_init() to avoid
board hang in SPL.
While at it remove explicit in-code console/debug UART pinmuxing (uart1
and its pinmuxing are already marked as u-boot,dm-spl via device tree).

pinctrl_wdog already marked u-boot,dm-spl, so clean up board code.
The set_wdog_reset() function is not necessary as this is handled by
the imx_watchdog.c driver due to the 'fsl,ext-reset-output' property
being set.

The power/bd71837.h should no longer be included, since V1.1 SoM

Rename board_early_init_f() to board_early_init(), since this function
has nothing to do with actual board_early_init_f() as used throughout
U-Boot. The board_early_init() is function local to this board used to
configure UART and WDT pinmux. Wrap init_uart_clk() into this function
so that early UART init would be all in one place. Turn the function
into __weak one, so it could be overridden in case custom carrier board
uses different UART or needs custom IOMUX settings.

Move this out of the common header and include it only where needed. In
a number of cases this requires adding "struct udevice;" to avoid adding
another large header or in other cases replacing / adding missing header
files that had been pulled in, very indirectly. Finally, we have a few
cases where we did not need to include <asm/global_data.h> at all, so
remove that include.

We should not use typedefs in U-Boot. They cannot be used as forward
declarations which means that header files must include the full header to
access them.
Drop the typedef and rename the struct to remove the _s suffix which is
now not useful.
This requires quite a few header-file additions.

Use the `do_reset` implementation of `arch/arm/lib/reset.c` in SPL
instead. It is very close to what is done here, anyway, and plays
more nicely with the rest of U-Boot than adding a custom `do_reset`
implementation into board files.
`do_reset` from `arch/arm/lib/reset.c` calls `reset_cpu` with 0 as the
addr parameter while the boards are passing WDOG1_BASE_ADDR. This is
ok because the `reset_cpu` implementation uses WDOG1_BASE_ADDR by
default if 0 is passed in.

This adds initial minimal support for the Toradex Verdin iMX8M Mini Quad
2GB WB IT V1.0A module. They are now strapped to boot from eFuses which
are factory fused to properly boot from their on-module eMMC. U-Boot
supports booting from the on-module eMMC only, SDP support is disabled
for now due to missing i.MX 8M Mini USB support.
Functionality wise the following is known to be working:
- eMMC, 8-bit and 4-bit MMC/SD card slots
- Ethernet
- GPIOs
- I2C
Boot sequence is:
SPL ---> ATF (TF-A) ---> U-boot proper
ATF, U-boot proper and u-boot.dtb images are packed into a FIT image,
