ARM: i.MX8M: esdctl: fix LPDDR4 size calculation for nano
i.MX8MN has a bus width of 16-bit, not 32-bit, so adjust accordingly.
This fixes RAM size computation of i.MX8MN boards with LPDDR4 memory.
Suggested-by: Lucas Stach <l.stach@pengutronix.de>
Fixes: 7a05a7626d7f ("ARM: i.MX: add i.MX8MN (Nano) SoC support boilerplate")
