[PATCH v3 08/14] ARM: i.MX8M: esdctl: export imx8m_ddrc_sdram_size()

[Marco Felsch <m.felsch@pengutronix.de>]

imx8m_ddrc_sdram_size() returns the full memory size whereas
imx8m_barebox_earlymem_size() limits the size to 4GiB.

This can be useful in cases like fixing up the FDT memory size for
OP-TEE which uses the information to configure the TZASC accordingly.
