[U-Boot] [PATCH v3 00/57] ram: rk3399: Add LPDDR4 support

[Jagan Teki]

This is next revison of lpddr4 support on rk3399 compared to
previous set[1]. It has some changes based on the commit orders
and squashing few patches together and rest is same.

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

Changes for v3:
- squash set_rate code in one patch
- tested in Rockpro64 and Rock-PI-4
- order them in proper way
- rebase on master
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.
