sunxi: a133: dram: Align parameters terminology with Allwinner
There is a mistmatch between Allwinner's dram_para BSP definitions and the
parameters names in mainline u-boot for TPR1-3. What we call TPR1 is actually
MR22 while TPR2 is TPR0 and TPR3 is TPR1. MR22 does get written to the
corresponding register. This only concerns LPDDR4 support.
Introduce a new Kconfig entry for MR22 and proceed with the rename.
Update the only config currently using it.
See the list of parameters from the Allwinner BSP at the end of:
https://linux-sunxi.org/A133/DRAMC
Note that the H616/H6 code is coherent with this new TPR0 definition
(and does not use TPR1 and MR22).
