One of the lines from PCF857x is connected to the vdd line of MMC1
in DRA74x and DRA72x EVMs and is modelled as a regulator. If PCF857x
is not made as built-in, the regulator_get in omap_hsmmc fails making
it difficult to use MMC1 as rootfs.

Make PCF857x built-in.

By converting a few drivers to modules because they
won't be needed during boot anyways, we can shave off
about 700KiB of text.

Note that while at that, and after discussions with Tony
Lindgren, a few extra drivers were either removed because
they weren't needed, or added because they're useful for
debugging/testing.
