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

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

AMSv2 and AMSv1 lowmem put the codec buffer in IRAM so we need to adjust
the address : AS3525_PHYSICAL_ADDRESS macro will do just that

Better be safe than sorry, don't try to read/write outside our storage,
because we might overwrite the OF on the internal storage

it would still flash when the light was off
it turns out that if B5 is set to input the light can't be turned on
but we can still select between µSD slot and internal storage

The OF does this and while we don't have the documentation to be sure I think it's highly likely this is a low power mode referred to in one of the product "briefs".

This seems to make switching the uSD card to high speed timing much more reliable.

Some SD cards were having problems switching to 4 Bit widebus and this solution appears to remedy that.

These INT's shouldn't be unmasked until the transfer is just about to happen.

Change SD_SELECT/DESELECT_CARD commands to MCI_NO_RESP as we don't need a response here.
Renumber some command errors.

Use it in fuzev2 to improve some big delays (correct the biggest one to actually wait for the fifo to empty), and use it in the sd drivers.

Before the clock settings were fixed this setting actually caused the problem it now seems to solve.
Random freezups seem to be gone for clip+ at least.

We only use DMA transfers so we should not need to change/reset the FIFO configuration.
Also add comment showing what we set as the TX/RX watermarks.

XPD was being switched between SD-MMC interface and general i/o functions in the sd_enable() function similar to as3525v1.
Since the as3525v2's do not seem to use XPD as general i/o there's no need to switch it back.
