If the controllers were already enabled there was a chance we could try to read the MCI_CLOCK registers while the cards were buffering and then disable the controllers prematurely.
I guess funman knows and sees all!! Thanks funman.

Because we turn off the clocks to the SD controllers between disk accesses we were unable to read the MCI_CLOCK registers until there was a disk access. Now we can read them immediately.

Enabling/disabling of the NAF and IDE clocks is now grouped together as both are related to the internal SD.
Sequence for disabling SD now mirrors the enable sequence.
Comments added to make it easier to follow the configuration change for XPD from gpio to mci-sd and back.

We had 3 different references to the same value. Rockbox always uses a blocksize of 512 bytes for SD and we were using SECTOR_SIZE, SD_BLOCK_SIZE, & card_info[drive].blocksize to use this value. Now the only reference being used is SD_BLOCK_SIZE.

Flyspray: FS#10371
Authors: Fred Bauer and myself
Only enabled on e200v2 and Fuze (crashes on clipv1)

When read it returns all enabled interrupt sources
When written it enables interrupt sources for each bit set
So just like VIC_INT_EN_CLEAR, we don't have to read the previous value
before writing to it (VIC_INT_EN_CLEAR is write-only anyway)
Thanks to Fred Bauer for spotting

We don't need to check the FIFO for MCI_RX_ACTIVE because we don't experience problems reading from the SD cards.
We need the MCI_TX_ACTIVE FIFO check during writes because some SD cards spend longer times in the PRG state
programming the data that has been written to them.

We use wait_for_state() before any command that requires a state prior to being sent. Waiting after a transfer is not needed.

The crc check on responses to sd commands was being bypassed due to a SD_APP_OP_COND special case. Now a short response is returned
even if the crc check fails so we can check the busy bit. The send_cmd() function still returns a false value but it loads the response
variable with the cmd response.

- two essential parts of Sansa AMS drivers are optimzed away in newer gcc, so mark them volatile.
- use "r" instead of "i" (which is apparently invalid syntax) for the input list in some inline assembly

Patch by Boris Gjenero. Displays the current flowing into or out of the

connected.
