- Important bugfix for some Tegra platforms

UEFI programs like GRUB make change terminal colors which requires support
for ANSI escape sequences.

Let CONFIG_EFI_LOADER=y imply CONFIG_VIDEO_ANSI.

For automating testing we should be able to power off the test system.
The implementation of EFI_RESET_SHUTDOWN requires the do_poweroff()
function which is only available if CONFIG_CMD_POWEROFF=y.

Enable CONFIG_CMD_POWEROFF if PSCI reset is available.

Not all architectures(i.e. i.MXRT) support mxc_get_clock() and use DM_CLK
instead. So building could result in failure due to missing
mxc_get_clock().

Add i.MXRT compatible string and cpu type support to lpuart driver,
to use little endian 32 bits configurations.

Also according to RM, the Receive RX FIFO Enable (RXFE) field in LPUART
FIFO register is bit 3, so this definition should change to 0x08 as done
for i.MX8. It needs also to set baudrate the same way as i.MX8 does.

This driver assumes that lpuart clock is already enabled before probing
but using DM only lpuart won't be automatically enabled so add
clk_enable() when probing if CONFIG_CLK is defined. If clock is not
found, because DM is not used, let's emit a warning and proceed, because
serial clock could also be already enabled by non DM code. If clock is
found but cna't be enabled then return with error.

At the moment entry_point is set to image_get_load(header) that sets it
to "load address" instead of "entry point", assuming entry_point is
equal to load_addr, but it's not true. Then load_addr is set to
"entry_point - header_size", but this is wrong too since load_addr is
not an entry point.

So use image_get_ep() for entry_point assignment and image_get_load()
for load_addr assignment.

imx6ul-14x14-evk does not have a GPIO dedicated for reading the card
detect pin on the eSDHC2 port. In such cases the "broken-cd" property
must be passed, otherwise the card cannot be detected.

When no GPIO is used to read the card detect status the following
error is seen:

MMC:   FSL_SDHC: 0, FSL_SDHC: 1
Loading Environment from MMC... MMC: no card present
*** Warning - No block device, using default environment

Fix it by handling the "broken-cd" property in the same way
that drivers/mmc/sdhci.c does, which considers that the SD card
is present when the "broken-cd" property is passed.

Tested on a imx6ul-evk board.
