the MUSB IP is always OTG, so there's no point
in adding so many ifdefs on the code. Drop those
and always compile the driver for OTG support.
This also allows us to drop the useless "driver
mode" choice. For doing that, we need to make
musb depend on both Host and Peripheral side.

Some of these workarounds are already in place, but labeled as affecting
all BF52x parts. Since we have official anomaly numbers now, use those
defines. And since writing to the FIFO has a similar hang issue as reading
from the FIFO, implement the workaround there too when necessary.

Since we can't work around anomaly 05000380, throw a build error up and
instruct the user to use a different mode.

Add some helpful notes about how the driver works around different
anomalies that exist in the on-chip host controller.

- replace MUSB_FIFOSIZE register to MUSB_TXCOUNT, cause no MUSB_FIFOSIZE
register on Blackfin
- use #ifdef to replace #if defined()
