Some platforms are incapable of triggering on level interrupts. Add a
platform quirks member in the platform data structure, as well as an
edge interrupt quirk which can be set on such platforms.
When the interrupt is requested with IRQF_TRIGGER_RISING, IRQF_ONESHOT
cannot be used, as we might miss interrupts that occur after the FW
status is cleared and before the threaded interrupt handler exits.
Moreover, when IRQF_ONESHOT is not set, iterating more than once in the
threaded interrupt handler introduces a few race conditions between this
handler and the hardirq handler. Currently this is worked around by
limiting the loop to one iteration only. This workaround has an impact
on performance. To remove to this restriction, the race conditions will
need to be addressed.

Clean up the boot sequence code & fix the following issues:
1. Always read the registers' values and set the relevant bits instead of
zeroing all other bits
2. Handle cases where wl1271_top_reg_read returns an error
3. Verify that the HW can detect the selected clock source
4. Remove 128x PG10 initialization code
5. Configure the MCS PLL to work in HP mode

Support building wl1271-equipped boards without building the
wl1271 driver itself, e.g.:
CONFIG_MACH_OMAP_ZOOM3=y
CONFIG_WL12XX is not set

The wl1271 device is using a reference clock that may change
between board to board.
Make the ref_clock parameter configurable by board settings
instead of having a hard coded value in the sources.

Add a simple mechanism to pass platform data to the
SDIO instances of wl12xx.
This way there is no confusion over who owns the 'embedded data',
typechecking is preserved, and no possibility for the wrong driver to
pick up the data.
Originally proposed by Russell King.
