Use LPDDR4-100 sdram timings dtsi for RockPI-4 board.
All these timings are processed during TPL stage of rock-pi-4 board,

Use DDR3-1866 2GB ddr timings dtsi for 1GB NanoPi Neo4 board.
Since sdram rk3399 support dynamic stride and rank detection it
can able to detect 1GB ddr eventough the timings are meant for
dual channel, 2GB size.
Bootchain after and before this change are:
TPL -> SPL -> U-Boot proper
rkbin -> SPL -> U-Boot proper
This certainly fix the second channel data training initialization
since we have dynamic rank, stride where second channel capabilities
are clear or memset to 0.

Unlike rest of dram type chips, LPDDR4 initialization start
with at board selected frequency (say 50MHz) and then it
switches into 400MHz and 800MHz simultaneously to make the
proper sequence work on each channel with associated training.
The lpddr4 set rate sequnce will follow by setting lpddr4
- dq out
- ca odt
- MR3
- MR12
- MR14
registers sets in sequential order.
Here is sameple log about LPDDR4-100 init sequence in Rockpro64:
Channel 0: LPDDR4, 50MHz
BW=32 Col=10 Bk=8 CS0 Row=15 CS1 Row=15 CS=2 Die BW=16 Size=2048MB
Channel 1: LPDDR4, 50MHz
BW=32 Col=10 Bk=8 CS0 Row=15 CS1 Row=15 CS=2 Die BW=16 Size=2048MB
256B stride
channel 0 training pass
channel 1 training pass
change freq to 400 MHz 0, 1
channel 0 training pass
channel 1 training pass
change freq to 800 MHz 1, 0
This patch add support to this init sequence via lpddr4 set rate
by taking sdram timing parameters from 400, 800 .inc files.

DDR set rate can be even required for lpddr4 and we
need to keep the lpddr4 code to compile only for relevant
boards which do support lpddr4.
For this requirement, and for code readability handle
data training via sdram_rk3399_ops with .set_rate and
same will update in future while supporting lpddr4 code.
