[RFC 0/6] improve OF_PLATDATA support

[Walter Lozano]

When using OF_PLATDATA dtbs are converted to C structs in order to save
space as we can remove both dtbs and libraries from TPL/SPL binaries.

This patchset tries to improve its support by overcoming some limitations
in the current implementation

First, the support for scan and check for valid driver/aliases is added
in order to generate U_BOOT_DEVICE entries with valid driver names.

Secondly, the way information about linked noded (phandle) is generated
in C structs is improved in order to make it easier to get a device
associated to its data.

Lastly the the suport for the property cd-gpios is added, which is used to 
configure the card detection gpio on MMC is added.

This implementation is based in discussion in [1] and [2]
