This change is also coherent with the structure in kernel.

mx6: ddr: Allow changing REFSEL and REFR fields

Currently MX6 SPL DDR initialization hardcodes the REF_SEL and
REFR fields of the MDREF register as 1 and 7, respectively for
DDR3 and 0 and 3 for LPDDR2.

Looking at the MDREF initialization done via DCD we see that
boards do need to initialize these fields differently:

$ git grep 0x021b0020 board/

So introduce a mechanism for users to be able to configure
REFSEL and REFR fields as needed.

Keep all the mx6 SPL users in their current REF_SEL and REFR values,
so no functional changes for the existing users.

arm: mx6: cm_fx6: detect 1GB DRAM correctly on solo

The 1GB DRAM configuration on mx6 solo uses 2 chip selects, but
the code tests 1GB DRAM configuration as if it is all present on one
chip select, and thus cannot see the full range of available memory.

Refactor the check to detect 1GB DRAM correctly.
