When using variadic macros there's no need for IF_MD2/IF_MV2 to deal
with function parameters. IF_MD/IF_MV are enough.
Throw in IF_MD_DRV/ID_MV_VOL that return the parameter if MD/MV, or 0
if not.

Mostly for the sake of reducing latency for audio servicing where other service
routines can take a long time to complete, leading to occasional drops of a
few samples, especially in recording, where they are fairly frequent.
One mystery that remains is GPIOA IRQ being interrupted causes strange
undefined instruction exceptions, most easily produced on my Fuze V2 with a
scrollwheel. Making GPIOA the top ISR for now, thus not interruptible, cures it.
SVC mode is used during the actual calls. Hopefully the SVC stack size is
sufficient. Prologue and epilogue code only uses the IRQ stack and is large
enough.
Any routine code that should not be interrupted should disable IRQ itself from
here on in.

High-speed mode is only half implemented (sd controller still uses normal speed) and causes card detection problems.

The number of blocks could have been checked while the card was not initialized yet.

Restore access to the last AMS_OF_SIZE == 0xF000 sectors of internal drive

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.

database update or copy between the 2 drives 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

not much difference for 1 or 8 sectors at a time
