... to avoid loosing characters when pasting text into the serial console.
This allows to remove the workaround to disable the vidconsole output

Add Serial Download Protocol support as it is a useful method to
load flash.bin to RAM and run it via 'uuu'.
With this patch, it is possible to start both U-Boot SPL and U-Boot
proper using the following 'uuu'command:
$ uuu -brun spl flash.bin
Based on a patch from Marek Vasut for the imx8mm-mx8menlo board.
Also, to fit the SPL binary into the internal RAM, select CONFIG_LTO
to reduce its size.

Enable DM USB, DM PHY and USB gadget support in imx8mm-mx8menlo SPL
to let the board continue SDP loading of second stage after the first
stage was loaded by BootROM SDP implementation. It is not possible to
jump back into BootROM v1 and let the BootROM implementation continue
the SDP loading, all this has to be performed by the U-Boot CI HDRC
controller driver and SDP protocol implementation, both of which fit
into the SPL just barely.
With this patch, it is possible to start both U-Boot SPL and U-Boot
using e.g. uuu on this board as follows:
$ uuu -brun spl flash.bin

The current implementation of spl_board_init() USB boot handling is
not correct, the MX8MM BootROM v1 does not support SDP load when
re-entered from U-Boot SPL, it is up to U-Boot to perform the next
stage load using its own internal CI gadget driver and SDP protocol
implementation. Drop the spl_board_init() to let SPL continue with
normal load in case the SDP support is enabled.

It turns out that it is not necessary to declare the VSELECT signal as
GPIO and let the PMIC driver set it to a fixed high level. This switches
the voltage between 3.3V and 1.8V by setting the PMIC register for LDO5
accordingly.
Instead we can do it like other boards already do and simply mux the
VSELECT signal of the USDHC interface to the pin. This makes sure that
the correct voltage is selected by setting the PMIC's SD_VSEL input
to high or low accordingly.
