[PATCH 11/23] ARM: i.MX8M: esdctl: drop ddrc base from imx8m_ddrc_sdram_size

All i.MX8M use the same DDRC MMIO address. Therefore drop the ddrc param
from imx8m_ddrc_sdram_size() and set it locally.
While on it drop the param from _imx8m_ddrc_add_mem() as well since it
is no longer needed to be passed to imx8m_ddrc_sdram_size().
