The i2c-hid driver has been split in two. Let's enable both halves.

the driver even more
confused about what it's doing.
The SPI core in general assumes that setting chip select is a simple
operation that doesn't fail. Yet another reason to just reconfigure
the chip select line as GPIOs.

Changes in v3:
- xfter => xfer
If we're using geni to manage the chip select line (don't do it--use a
GPIO!) and we happen to get a timeout waiting for the chip select
command to be completed, no errors are printed even though things
might not be in the best shape. Let's add a print.

Changes in v4:
- Emphasize in the commit message that this itself doesn't fix anything
wrong rate (maybe it's rounding up instead of
down), this will make it much more obvious what's going on.
NOTE: we have to be a little careful here because the "actual_clock"
field shouldn't include the multiplier that sdhci-msm needs
internally.
