Linus Walleij 49adc0cacb mmc: mmci: refactor ST Micro busy detection 
The ST Micro-specific busy detection was made after the assumption
that only this variant supports busy detection. So when doing busy
detection, the host immediately tries to use some ST-specific
register bits.

Since the qualcomm variant also supports some busy detection
schemes, encapsulate the variant flags better in the variant struct
and prepare to add more variants by just providing some bitmasks
to the logic.

Put the entire busy detection logic within an if()-clause in the
mmci_cmd_irq() function so the code is only executed when busy
detection is enabled, and so that it is kept in (almost) one
place, and add comments describing what is going on so the
code can be understood.

Tested on the Ux500 by introducing some prints in the busy
detection path and noticing how the IRQ is enabled, used and
disabled successfully.
