- During merge to imx_v2020.04_5.4.24_2.1.0 branch the '&usb_dwc3_1'
  node reference was duplicated in the pitx-imx8m device tree. As a
  result, USB port 1 support was broken. Fix this and remove superfluous
  usb_dwc3_1 reference.

- Fix struct definitions from new u-boot
  Environment data structure were renamed in v2020.04. Fix environment
  env_entry structure definitions.
- Remove memory setup functions
  Memory setup functions 'dram_init', 'get_effective_memsize' and
  'dram_init_banksize' are defined within mach-imx specific memory
  driver and thus removed here.
- Fix some device node names
  Some device nodes are renamed in underlying dtsi files. Fix
  references to these nodes.
- Fix SPL build
  fix include files used
  fix PMIC configuration settings to allow build with PMIC support.

- There are other automatic environment variable available:
  arch=arm
  soc=imx8m
  soc_type=imx8mq
  cpu=armv8
  So, no additional 'core_variant' variable is necessary.

This reverts commit 480e495505ef9a03af3f2b509d9bf845470bac43.

Toogle the TPM_PCI_RST# (GPIO3_IO2) line for 70ms.

- Enable ums (USB Mass Storage) support that allows to mount onboard
  mass storage devices like eMMC and SD card on external host machine.
  This can be a convenient method to install software on onboard devices.
- Remove configuration settings duplicated (and outdated) in pitx-imx8.h
  config file.

- This creates environment variable 'ver' that shows the U-Boot
  version the same way it is printed by the 'version' command.
- Note that module release string (e.g. PITX-IMX8M-R10) must be
  introduced to UBOOTRELEASE string by setting and pasting
  CONFIG_LOCALVERSION appropriately during build procedure, e.g.
  echo CONFIG_LOCALVERSION=\"-<release-tag>\" >>.config

- Use 'board_serial' environment variable to read correct serial number
  as stored in VPD area.
Signed-off-by: Thomas Schaefer <thomas.schaefer@kontron.com>

- Normally, Kontron modules with VPD data stored on embedded KEU
  EEPROM set the 'serial#' environment variable to the value found
  in the 'Serial Number' entry of the SMBIOS block type 2.
- However, on some i.MX8 based modules, the NXP fastboot implementation
  sets 'serial#' in the 'fastboot_setup' function _before_ KEU VPD data
  EEPROM is read. As serial# is write once, it cannot be overridden by
  the value found in VPD data.
- So introduce the new 'board_serial' environment variable that to
  store the serial number from VPD data area. Board specific 'getSerNo'
  function must be adapted to read 'board_serial' from environment
  instead of 'serial#'.
- Keep also to setting the 'serial#' variable as before to be backward
  compatible and to have the 'serial#' variable still set in case that
  FASTBOOT might not have been configured in the bootloader.

- Read i.MX cpu type using standard 'get_imx_type' functioin.
- Convert string to lowercase and set core variant appropriately.
- Remove blank characters from string as the core_variant variable
  could be used to select appropriate device tree before OS boot.
