A new driver uclass is created to handle the reboot mode control.
The new uclass driver is updating an environment variable with the
configured reboot mode. The mode is extracted from a map provided
at initialization time. The map contains a list of modes
and associated ids.

As the deadline for migration to DM_USB, when using a USB host
controller has now gone two years past the deadline, enforce migration.
This is done by:
- Ensuring that all host controller options (other than the very legacy
old MUSB ones) now select USB_HOST. USB_HOST now enforces DM_USB and
OF_CONTROL.
- Remove other parts of Kconfig logic that had platforms pick DM_USB.
- To keep Kconfig happy, have some select statements test for USB_HOST
as well.
- Re-order some Kconfig entries and menus so that we can cleanly pick
host or gadget roles. For the various HCD options that have platform
glue options, group them together and update dependencies in some
cases.
- As SPL_DM_USB is not required, on platforms that had not yet enabled
it, disable it.

On MIPS the DRAM start address respectively CONFIG_SYS_SDRAM_BASE
is still used as a virtual, CPU-mapped address instead of being used
as physical address. Converting all MIPS boards and generic MIPS code
to fix that is not trivial. Due to the approaching deadline for
PCI DM conversion, this workaround is required for MIPS boards with
PCI support until the CONFIG_SYS_SDRAM_BASE issue could be solved.
Add a compile-time option to let the PCI uclass core optionally map
the DRAM address to a physical address when adding the PCI region
of type PCI_REGION_SYS_MEMORY.

Section "59.5.3 Configure Watchdog" provides the following example:
DisableInterrupts; //disable global interrupt
WDOG_CNT = 0xD928C520; //unlock watchdog
while(WDOG_CS[ULK]==0); //wait until registers are unlocked
WDOG_TOVAL = 256; //set timeout value
WDOG_CS = WDOG_CS_EN(1) | WDOG_CS_CLK(1) | WDOG_CS_INT(1) |
WDOG_CS_WIN(0) | WDOG_CS_UPDATE(1);
while(WDOG_CS[RCS]==0); //wait until new configuration takes effect
EnableInterrupts; //enable global interrupt
Update U-Boot WDOG driver to align with i.MX7ULP reference manual.
Use 32 bits accessing to CS register. According to RM, the bits in
this register only can write once after unlock. So using 8 bits access
will cause problem.

According to i.MX7ULP Reference Manual the second word write for both

The current code is using writel() function which has a DMB barrier to
order the memory access. The DMB between two words write may introduce
some delay in certain circumstance, causing a WDOG timeout due to 16 bus
clock window requirement.
Replace writel() function by __raw_writel() to achieve a faster memory
access and avoid such issue.
