mmc: Fix omap compile by replacing dev_name with dma_dev_name 
This patch fixes error:

drivers/mmc/host/omap.c: In function 'mmc_omap_get_dma_channel':
drivers/mmc/host/omap.c:1038: error: called object 'dev_name' is not a function

Commit 06916639e2 adds a function
called dev_name. This will cause a name conflict as dev_dbg calls
dev_name(((host->mmc)->parent)).

This same issue should not affect other drivers as they don't seem
to use dev_name with dev_dbg.

Thanks to Paul Walmsley <paul@pwsan.com> for figuring this one out.

MMC: OMAP: Do not busy wait for end of command for ever 
The limit was a fixed 100k limit in the busy loop, which is not
accurate. It would better to have time limit for the worst case
which occurs when sending 80 cycles at 400 kHz and takes about
200 microseconds, so limit the max time spend in the busy loop
for some 250 microseconds.

MMC: OMAP: Start new commands from work queue instead of irq 
Use work queues for starting new commands instead of starting them
directly from irq handler. The command scheduling needs to be delayed
a bit for some cards which should not be done from an interrupt.

MMC: OMAP: Use tasklet instead of workqueue for cover switch notification 
The cover waitqueue is occasionally scheduled twice from timer
and the interrupt and oops follows. It would have been possible
to fix this problem with spinlocks but using tasklet was a dropin
solution with no need for locking.

This path also adds some cleanups.

MMC: OMAP: Abort stuck commands 
When a card is removed while it is being accessed, a command can get stuck so
that no timeout or end of command interrupt ever occurs. The command getting
stuck is almost always CDM12, but also the other commands can get stuck. Catch
a stuck command with a timer and try sending the initialization stream until
the controller starts running again and responds with the end of command
status.
