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.

Otherwise gcc will whine about epnum/dma_reg being unused when building
for BF54x parts.

The Blackfin port doesn't support HAVE_CLK and the musb driver works fine
with support stubbed out, so take the existing Blackfin clk stubs and move
them to common musb code so we can drop the Kconfig dependency.

Let the otg_transceiver in MUSB be managed by an external driver;
don't assume it's integrated. OMAP3 chips need it to be external,
and there may be ways to interact with the transceiver which add
functionality to the system.
Platform init code is responsible for setting up the transeciver,
probably using the NOP transceiver for integrated transceivers.
External ones will use whatever the board init code provided,
such as twl4030 or something more hands-off.

Make sure we program the correct values in only when necessary.

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