[PATCH v3 0/6] mx6cuboxi: enable OF_PLATDATA with MMC support

[Walter Lozano]

The SPL in iMX6 boards is restricted to 68 KB as this is the free available
space in OCRAM for most revisions. In this context, adding OF_CONTROL and
DM increases the SPL size which could make it difficult to add specific
features required for custom scenarios.

These patches aim to take advantage of OF_PLATADATA in order to reduce the
SPL size in this scenario, by parsing DT data to generate platdata
structures, and thus removing the overhead caused by DT and related
libraries.

This series is focused in MMC driver, which is used for boot in boards such
as Cubox-i. Also, in order to support CD, the OF_PLATDATA support is also
implemented on GPIO driver.

After applying this setting the SPL reduction is 5 KB, which partially
compensates the increment due to DM.

Changes in v3:
- Fix commit message
- Rework to resolve merge conflicts
- Change #ifdef to if when possible

Changes in v2:
- Improve commit message with footprint reduction
