[U-Boot] [PATCH v2 1/3] disk/part.c: Make features optional

[Matthew McClintock]

If we don't want to build support for any partition types we can now
add #undef CONFIG_PARTITIONS in a board config file to keep this from
being compiled in. Otherwise boards assume this is compiled in by
default

v2: Fix patch to apply to current tree

Note: This includes the fixes for MMC only. USB/SATA/etc need to do
something similiar
