This patch cleans-up TUSB fifo access and uses readsl/writesl()
when possible. It also has hooks for some further optimization,
notably synchronous burst access using PIO.

Running a tusb6010 system in host mode would fail with
testusb -a -t12 -c1 most of the time with BABBLE errors.

Turns out this was caused by incorrect handling of TX
FIFONOTEMPTY, where the code did not wait for it to clear.

This patch introduces musb_h_tx_flush_fifo(), and makes
musb_host.c to use it.

Babble is a non-recoverable error condition and we

Async RX DMA on tusb6010 will eventually corrupt the XFR_SIZE
register. This patch blocks DMA transfers for async RX DMA.

DMA callback can manually transfer remaining 1 - 31 bytes
after DMA transfer using PIO. This allows transferring
a wider range of sizes with DMA.

This needs to be tested with sync DMA transfers as
PIO may not be mixed with sync DMA.

With this patch tusb can transfer sizes that are not
multiples of 32 bytes.

This patch allows host to try to use DMA on tusb6010.

Please note that until tusb6010 DMA size limitations

This can be used on systems that don't use ID pin, or have mini-B
connector.

For example, to force N800 into host mode with non-standard mini-B
to mini-B cable connected to a powered hub:

Note that connected mini-A cable cannot be forced to peripheral
mode as the ID pin is grounded by the cable. Also note that
any VBUS load above the 100mA will cause the host mode to fail.

The usage of the external oscillator is handled already by
sleep_block and doesn't require any extra checking.
Incidentally this fixes a bug where N800 wouldn't enter retention
the first time the display would blank.
