This uclass is intended for devices that do not need any features from the
uclass, including binding children.
This will typically be used by devices that are used to bind child devices
but do not use dm_scan_fdt_dev() to do it. That is for example the case of
several USB wrappers that have 2 child devices (1 for device and 1 for
host) but bind only one at a any given time.

The EHCI iMX6 driver is only partly converted to DT probing and
still uses a tremendous amount of hard-coded addresses. Worse,
the driver uses hard-coded SoC-model-specific base addresses, which
are derived from values protected by SoC-specific macros, hence the
driver is also compiled for a specific SoC model. Even worse, the
driver depends on specific sequential indexing of the controllers,
from which it derives offsets in the PHY and ANATOP register sets.

However, when the driver is probed from DT, the indexing is not
correct. In fact, each controller has index 0. This patch derives
the index for DT probing case from the controller base addresses,
which is not the way this should be done, however it is the least
intrusive approach, favorable this close to release.

The necessary steps to convert this driver fully to DT probing are
described inside the patch, however this should be done in the next
release and depends on iMX clock driver patches.

There is a regression seen on Poplar platform, which doesn't even show
a U-Boot version banner on booting.  It turns out that due to landing
of commit 3a7c45f6 ("simple-bus: add DM_FLAG_PRE_RELOC flag to
simple-bus driver"), we need to increase SYS_MALLOC_F_LEN from its
default size 0x400, as pre-relocation requires more memory there.  Let's
increase SYS_MALLOC_F_LEN to 0x4000 to fix the regression.

debug_uart_init() is called from spl_board_init(), which is only
compiled for SPL. For U-boot proper, _debug_uart_init() is unreachable,
so dropped by the dead code elimination.

Now that 64-bit SoCs of this SoC family no longer support SPL,
debug-uart-ld20.c is never compiled.

STM32 MCU fixes/cleanup:
- Fix SPL console for STM32F769 Discovery
- Fix Memory Protection Unit size for STM32F4 series
- Cleanup DT for STM32F746 Discovery

The MPU region dedicated for SDRAM for STM32F4 SoCs family
was set to 16MB, but STM32F429 Evaluation board have 32MB of SDRAM.

When kernel starts, only first 16MB of SDRAM are configured with XN
(eXecute Never) bit disabled, whereas kernel is using 32MB.
To avoid such situation in the future, extend this MPU region to 512MB
as for STM32F7/H7.

It fixes the following user land exception on STM32F429 Evaluation
