[U-Boot] [PATCH v2 2/2] colibri_imx7: prime get_ram_size() using imx_ddr_size()

[Marcel Ziswiler]

From: Fabio Estevam <festevam at gmail.com>

Rather than passing a hardcoded maxsize to the generic get_ram_size()
function use the i.MX 7 specific imx_ddr_size() function, which extracts
the memory size at runtime by reading the DDR controller registers.

This is a purely cosmetic change as the generic get_ram_size() function
already took care of properly automatically detecting 256MB, 512MB or 1GB
modules.
