[PATCH v2 2/3] ARM: i.MX8M: esdctl: use common compatible to detect i.MX8MQ/MM/MP DDRC

All i.MX8M* DDRC nodes are compatible to "fsl,imx8m-ddrc". As the memory
size detection works the same on most of them, with the only exception
being the i.MX8MM, which only has a 16bit data bus, there is no need to
match the more specific compatibles for i.MX8MQ/MM/MP.
