- change buffer alignement to 32 bytes (not sure if it's useful)
- flush rx fifo on reset
- use AS3525_PHYSICAL_ADDR for DMA
- reset endpoints structure states on reset
- force full speed for debugging purpose
- add more debugging code

Without this change the backlight would be enabled but the screen would
show the last content displayed before the screen went off

The driver is stable so we can use error codes for debugging
Fix 2 problems in error code path:
- release sd mutex
- release dma module when needed

fix DMA buffers when the src/dst is in IRAM
It worked fine because all the buffers are in DRAM, and the virtual
address happens to be the physical address

(USB stack is not used by default)
This makes debugging the USB driver easier

Users will have to reboot to OF manually or to power off, and then plug USB
No message is displayed because usb_detect() is run from a tick
This lacks documentation but should be OK for Unstable devices, and
will hopefully prevent clueless users from opening their devices and
breaking them definitely, instead of waiting for the battery to power
off.

If the card is not actively deselected on newer Fuzev2, frequent
switches between internal storage and µSD will lock up.

playing from µSD now works to some degree
database update or copy between the 2 drives lock up

fuzev2 button_read_device() runs in interrupt context so writes are atomic

The new controller framebuffer (different from what is in clipv1/clipv2 and some clip+) has 128 columns, the old has 132 columns and is centered on the screen.

There was a stupid bug in endpoint listing which caused random cancelling of EP0 transfers. The new scheme to handle EP0 transfers should avoid an unexpected setup packet which might cause a deadlock or confuse the core.
There is still an issue with the cancel_transfers function is still.

There is still a problem after the set address request which makes the driver working randomly.
I still didn't manage do get a proper disconnect interrupt.
From time to time, when unplugging cable, neither rockbox nor usb driver reports disconnect even.

On tx underruns, a write is aborted early, leaving the dma channel active.
We didn't explicitly disable it, so there were still 4 words in the dma
controller fifo, corrupting the retried write.
To chase this bug I added verify after write, if no one sees write errors in
the next week or so this can be removed.

We always need to write MCI_ARGUMENT register so if the command expects
no argument just set the function argument to 0
Code is now similar to as3525v2
hint: merging the 2 and/or all the SD drivers would be nice
