- Set the LED_2_SEL bits [11:8] in DP83867IR LED Configuration
  Register 1 to 0b1011 (link established, blink on activity) from
  default value 0b0001. Same settings are configured for GBE1 PHY
  when I210/I211 is activated in linux.
- This fixes KDP#81891 request for the pITX-iMX8M.

- 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.
