ARM: dts: stm32mp1: DDR config v1.44

Update DDR configuration with the latest update:

- PUBL_regs: DXnGCR[0]= according to ddr_width to disable Byte
                        lane 2/3 in 16bit
- fix LPDDR2/3 timing_calc to step RL/WL in relaxed
  timings mode
- 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.
    For example @533MHz RL/WL (relaxed) = 9/5 for LPDDR2/3
    and correction to MR2 accordingly
- DDR_PCFGQOS1_1: port1 timeout relaxed from 0x00 to 0x40,
  for LTDC.
- DDR_PCFGWQOS0_0: change vpr level from
  11 to 12 in order to include the CPU on
  the variable priority queue.
- DDR_SCHED: fix to consider 13 levels  (13 levels - 1 = 0xC)
