Store the bus cookie in the mmc_disk driver and pass it to the bus
manager when executing commands. This avoids calling into the device
manager at each read and write operation. The code to get the cookie
from mmc_disk isn't so nice since it needs to access the grandparent
device (the mmc bus root), it would be simpler if this cookie would be
available directly from mmc bus devices.
We can get card removal and card insertion interrupt at the same time
due to insufficient hardware debouncing (the SDHCI spec says we
shouldn't, but it happens on Ricoh controllers. Can't blame them, they
don't advertise themselves as compliant with the spec). So, check the
card status from the interrupt handler and ignore the incorrect
interrupts.
Fix unreliable card initialization: power must be turned on before
starting up the SD clock. Remove a now unneeded delay that was added in
an attempt to avoid initial instability.
