'select' does not work on config options in a 'choice', so currently it is
possible to enable FB_MB862XX_LIME without FB_LITTLE_ENDIAN.

We cannot replace the 'select FB_LITTLE_ENDIAN' without also changing
FB_FOREIGN_ENDIAN from 'select' to 'depends on', otherwise we will get
a recursive dependency.

Note that, if we remove the select / dependency, the kernel will compile
with FB_MB862XX_LIME=y and FB_LITTLE_ENDIAN=n so if it would be
better to remove the select, please advise as I do not have the hardware
to runtime test this.

This dead select was found by kconfirm, a static analysis tool for Kconfig.
