commit 49ea0ff5 (49ea0ff5) introduced CONFIG_SYS_MMC_ENV_PART into mx6qsabresd.h
to store the mmc partition, but in order for it to have effect we should place
it into 'mmcpart' variable.

Also add CONFIG_SYS_MMC_ENV_PART into mx6qsabreauto.h.

Create function which converts SSP bus number to SSP register pointer.
This functionality is reimplemented multiple times in the code, thus
make one common implementation. Moreover, make it a switch(), since the
SSP ports are not mapped in such nice linear fashion on MX23, therefore
having it a switch will simplify things there.

Commit fb6a9aab (LCD: display 32bpp decompressed bitmap image)
broke the check that allowed U-Boot to display 8 bpp BMPs on a 16
bpp LCD screen, effectively turning this feature off.

Restore this feature by changing the check back to the same meaning
it originally had.
To avoid future confusion, the check has also been rephrased to make
its meaning clear.

Currently the CLAA WVGA panel is supported, but this panel has to be purchased
separately, so using the DVI output as the default would allow more people to

If someone still wants to use the CLAA WVGA, just set the panel variable as:
