Make first step in DT/DM migration. Enable OF_CONTROL only for the main
U-Boot image for now.
Remove mmc_init_main() because board_mmc_init() is not called when
DM_MMC is enabled.
DM_MMC requires DM_GPIO for card-detect to work. That in turn makes gpio
request mandatory. Add code to request/free gpios in platform code.
MMC devices are now numbered according to DT. The SD card is 1, and eMMC
is 2. Account for that in board_mmc_get_env_dev(), BOOT_TARGET_DEVICES,
and has_emmc().
DM_MMC requires BLK. However, the (BLK && !DM_USB) combination disables
USB_STORAGE. Enable DM_USB to preserve USB functionality. Add also
DM_REGULATORS for the USB power controller. This allows us to drop
board_ehci_hcd_init() and setup_usb().
Runtime selection of DT is necessary because of the i.MX6QD vs i.MX6SDL
incompatibility. DT selection does not rely on GPIOs, since DM_GPIO
depends on DT. Instead, we take one "fully featured" DT of each variant.
That should be enough to boot from both SD card and eMMC.
Since we don't select the exact DT, override the generic
show_board_info() that shows the selected DT 'model' field.

Import fsl-imx-audmux.h from Linux as of v5.4-rc6. The header is

DM for PCI pulls DM for ethernet that also needs other changes described
below to build u-boot and keep existing functionality - ability to update
MAC addresses of FEC ethernet adapter and I210 adapter connected to the
Marvell switch.
- fec_mxc driver with DM needs PHYLIB;
- configuration items are moved from ge_bx50v3.h to ge_bx50v3_defconfig;
- FEC is marked as eth0 because it is always present, so indices changed:
I210 are still probed in the same order;
- board_eth_init() was used by legacy ethernet, setup for enet iomux and
pcie is moved to the board_late_init();
- pci_init() is called from the board_late_init() to initiate PCI bus
probing, so I210 devices are propagated to the device tree;

On K3 devices there are 2 conditions where R5F can deadlock:
1.When software is performing series of store operations to
cacheable write back/write allocate memory region and later
on software execute barrier operation (DSB or DMB). R5F may
hang at the barrier instruction.
2.When software is performing a mix of load and store operations
within a tight loop and store operations are all writing to
cacheable write back/write allocates memory regions, R5F may
hang at one of the load instruction.
To avoid the above two conditions disable linefill optimization
inside Cortex R5F which will make R5F to only issue up to 2 cache
line fills at any point of time.
