This driver has been developed as a separate module starting

Separation has been mainly driven from change in endianness.
Can't we have a way to define the endianess at build or even runtime?
We have plenty of that elsewhere in the kernel.
well, the base sdhci layer wants to access byte-size fields of the
esdhc controller registers.
But this same Freescale esdhc controller may be found in 2
flavors, big-endian or little-endian organized.
So in this driver i am actually correcting byte-addresses to
access the wanted byte-field in the big-endian hw controller.
So this is a bit different from a be-le endian swap of a
long or a short that the kernel is organized to do..
