The DWMAC clock in i.MX8M Plus were so far configured via ad-hoc
architecture code. Replace that with DM clock instead. This way,
the driver claims all its required clock, enables and disables
them, and even gets the CSR clock rate and sets the TX clock rate,
without any need of architecture specific register fiddling. Drop
the architecture specific code while at it too.
The adjustment here is modeled after STM32MP15xx clock handling
in this driver.

The driver currently only waits for DMA_MODE SWR bit to clear itself.
This is insufficient e.g. on i.MX8M Plus, where the MAC must be reset
before IOMUX GPR[1] content is latched into the MAC and used. Without
the proper reset, the i.MX8M Plus MAC variant does not take the value
in IOMUX GPR[1] into account, which makes it impossible e.g. to switch
interface mode from RGMII to any other.
Since proper reset is desired in general to put the block into defined
state, always assert the DMA_MODE SWR bit before waiting for the bit
to clear itself.

The dm_gpio_free() is never called, because for stm32, the phy_reset_gpio
pointer is never valid. This is because only tegra186 ever claims the
phy_reset_gpio, all other platforms use the PHY framework to reset the
PHY instead. Drop the dm_gpio_free() and dm_gpio_is_valid().

Update the distro config env memory layout for the Colibri iMX8X:
- kernel_comp_addr_r=0xb0000000 temporary area for uncompressing (ie FIT
images or Image.gz booted using booti)
- kernel_comp_size=0x08000000
- loadaddr=0x95400000 avoiding any reserved areas located before that
- fdt_addr_r = loadaddr + 128MB - allows for 128MB kernel
- scriptaddr = fdt_addr_r + 512KB - allows for 512KB fdt
- ramdisk_addr_r = scriptaddr + 512KB - allows for 512KB script
Idea of memory layout taken from commit a9f1e35bed
("apalis-imx8: update env memory layout").

The ocotp driver is available for regular and SPL builds using the
(SPL_)MXC_OCOTP configuration. Also, the ocotp driver does not support

But, for SPL builds, the SPL_MXC_OCOTP configuration depends on
SPL_MISC which implies on SPL_DM.
This commit replaces the dependency on SPL_MISC with SPL_DRIVERS_MISC.

Without this configuration enabled U-Boot corrupts the bad block table

because if CONFIG_SYS_NAND_USE_FLASH_BBT is not set, U-boot will store
bad blocks out of band, while the Linux driver for the iMX7 will store
them in band in a bad block table.

A385 BootROM treats strapping configuration 0x3f as invalid. When booting
fails (e.g. because of invalid configuration) then BootROM fallbacks to
UART booting.
Detecting BootROM fallback to UART booting is implemented in U-Boot since

So there is no need to define BOOT_FROM_UART_ALT constant and special
