Backport usage of a new KSZ9XX1 PHY by Apalis iMX6, the old driver
located in micrel.c still used by other boards. If a board
wants to use a new PHY the old one must be disabled.
Backported from:
commit f72e48ba4d98 ("board: apalis_imx6: Add KSZ9131 phy skew settings")

U-Boot typically tears down the display controller before handing
control over to Linux. On LCD displays disabling pixel clock leads to a
fading out effect with vertical/horizontal lines. Make sure to disable
back light before booting Linux.

Modify configuration for Tezi:
- Enable SDP in SPL and U-Boot
- Enable FDT relocation (in-place is causing issues with FIT images)
- Remove video output
- Use distroboot by default
- Boot from external SD cards by default
- Disable USB PID from config block (otherwise recovery mode download
in U-Boot stage fails)

In case USB serial downloader has been used to load U-Boot start the
serial download protocol (SDP) emulation. This allows to download
complete images such as Toradex Easy Installer over USB SDP as well.
This code uses the boot ROM provided boot information to reliably
detect USB serial downloader.

If the UART is used in DTE mode the RI and DCD bits in UCR3 become
irq enable bits. Both are set to enabled after reset and both likely
are pending.
Disable the bits also on UARTs not used in the boot loader to prevent
an interrupt storm when Linux enables the UART interrupts.

This adds a Kconfig SPL_SILENCE_CONSOLE which allows to suppress any
console output which in the normal program flow is printed in the SPL.
Error messages and the likes will still be printed.

Use a completely independent USB Product ID for SPL. This allows
to differentiate a SDP running in SPL and SDP running in a U-Boot
which could not read the config block successfully.

In the linux device tree we use 40Ohm drive strenght. So use the same
