[PATCH 1/4] [OMAP1] Add MMC board code common to HTC devices

[Cory Maccarrone <darkstar6262@gmail.com>]

This change adds the htc-mmc.c and htc-mmc.h files that
contain common setup code for many OMAP850-based HTC
smartphones.  This code is a port of the code used by
the linwizard project to support devices such as the
HTC Wizard, HTC Herald, HTC Opal, etc.
