ram: rk3399: add missing high row detection

For 2 GB LPDDR4 single-rank RAM with 16 rows, the Rockchip ddr init bin
prints:
"Bus Width=32 Col=10 Bank=8 Row=16 CS=1 Die Bus-Width=16 Size=2048MB"

U-Boot TPL prints:
"BW=32 Col=10 Bk=8 CS0 Row=16/15 CS=1 Die BW=16 Size=2048MB"

Add missing high row detection so that U-Boot TPL prints Row=16, same as
the Rockchip ddr init bin:
"BW=32 Col=10 Bk=8 CS0 Row=16 CS=1 Die BW=16 Size=2048MB"
