All i.mx6 boards seems to have moved to DM_USB, however gadget support
for mx6 is still pre-DM as CI_UDC isn't converted yet. To make this work
the usb otg controller used for gadgets needs to be usb number 0.
Add an alias for this directly in the main u-boot mx6qdl dtsi so it
doesn't need to be done for each board separately.

This fixes regressions wrt. usb gadget functionality in several boards
that have gadget functions enabled in their config, but no usb0 alias in
their device-tree.

This commit adds initial support for the Toradex Apalis iMX8QM 4GB WB IT
V1.0B module. Unlike the V1.0A early access samples exclusively booting
from SD card, they are now strapped to boot from eFuses which are
factory fused to properly boot from their on-module eMMC. U-Boot
supports either booting from the on-module eMMC or may be used for
recovery purpose using the universal update utility (uuu) aka mfgtools
3.0.

Functionality wise the following is known to be working:
- eMMC, 8-bit and 4-bit MMC/SD card slots
- Gigabit Ethernet
- GPIOs
- I2C

Unfortunately, there is no USB functionality for the i.MX 8QM as of yet.

- fix LPDDR2/3 timing_calc to step RL/WL in relaxed

- remove  LPDDR3 RL3 (optional) support vs  MR0[7]
  because MR0[7] can't be read instead  always apply
  worse RL/WL for LPDDR3 when freq < 166MHz)
- change  MR3 to 48ohm drive  for LPDDR2/3
- change default ZPROG[7:4] = 0x1 for LPDDR2/3 ,
  '0' is not allowed even when ODT not used
- use DQSTRN for LPDDR2/3 (it was not set in PIR)
- LPDDR3: set dqsge/dwsgx gate extension to 2,2
  like LPDDR2
-DDRCTRL.dfitmg0:
  + for LPDDR3 tphy_wrlat = WL (as LPDDR2)
  + improvement for relaxed mode vs  RL/Wl at corner case.

Without this U-Boot specific property, booting on Armada XP theadorable

not scanned, so the UART node is missing (and others).

I'm not adding this property in an *u-boot.dtsi file, since there is
none matching the generic rules for all files including this dtsi
file. So to not miss any of the boards using this dtsi file, I'm
adding it to this file directly, which makes the Linux merge a less
