Commit 4f8a066b5f (blockdev: Remove IF_*
check for read-only blockdev_init) added a usage of bdrv_is_read_only()
to sd_init(), which is called for versatilepb, versatileab and
xilinx-zynq-a9 machines among others with NULL argument by default,
causing the new qom-test to fail.
Add a check to prevent this.

IF_NONE allows read-only, which makes forbidding it in this place
for other types pretty much pointless.
Instead, make sure that all devices for which the check would have
errored out check in their init function that they don't get a read-only
BlockDriverState. This catches even cases where IF_NONE and -device is
used.

Add a cast to avoid potentially shifting into the sign bit of
a signed value, which is undefined behaviour in C.

The DMAContext is a simple pointer to an AddressSpace that is now always
already available. Make everyone hold the address space directly,
and clean up the DMA API to use the AddressSpace directly.

QEMU models two (of the three) ACMD41 has two modes, "inquiry" and
"first". The selection logic for which of the two is incorrect - it
compares != 0 for the entire argument value rather than only bits 23:0
as per the spec. Fix.

The end of transfer check was occurring and potentially returning before
the interrupt flag was checked. This means the interrupt will be missed
if it occurs on the last packet. Fix by checking for the interrupt
before checking for the end of transfer.

This message was printing out the data in decimal only, which is not
very friendly to the debugging developer. Add hex variant in
parenthesis to make it consistent with other similar messages in this
module.

The data_count variable was being reset on every transfer, including
DMA transfer resumptions. This is incorrect, it should only be set
on a new command.
Manifests as a bug when using ADMA and there is a timer delay between
ADMA frames where the fifo is left in a non empty state.
