This is the v2 set for supporting LPDDR4 with associated
features, wrt to previous series[1].

Thanks to
- YouMin Chen
- Akash Gajjar
- Kever Yang
for supporting all the help on this work.

On summary this series support
- Code warning and fixes
- rank detection, this would required to probe single channel 
  sdram configured in NanoPI-NEO4
- LPDDR4 support, tested in Rockpro64 and Rock-PI-4

Changes for v2:
- handle LPDDR4 code as part of CONFIG_RAM_RK3399_LPDDR4
- support data_training and set_rate via sdram_rk3399_ops
- add proper sys_reg_enc macros
- add new patch to rename variable sdram_params with params
- fix few commit messages

patch 0001 - 0034: fix code warnings, prints, new macros

patch 0035 - 0052: rank detection, sdram debug code

patch 0053: use DDR3-1800 on NanoPI-NEO4

patch 0054 - 0094: lpddr4 support

patch 0095: enable lpddr4 in Rockpro64

patch 0096: enable lpddr4 in Rock-PI-4

patch 0097: LPDDR4-100 timings

patch 0098: Use LPDDR4-100 on Rockpro64

patch 0099: Use LPDDR4-100 on Rock-PI 4
