[PATCH] arm: imx: mmdc_size: Increase row_max for imx8m

[Teresa Remmet]

As DDRC_ADDRMAP7_ROW_B16 and DDRC_ADDRMAP7_ROW_B17 are used
now for the row size calculation we need to increase row_max to 18.

For LPDDR4 this only works in combination with ram timings
created with recent configuration spreadsheet versions.
With older versions the register DDRC_ADDRMAP7 may not be set and
calculation will lead to wrong results even with this patch.

Fixes: dad2b5636bd8 ("ARM: imx: Add imx8 support for 18 bit SDRAM row size handle")
