The card firmware does not set the Command Download Ready interrupt bit
when IEEE PS mode is enabled, preventing the driver from sending
commands (such as the command to exit IEEE PS mode) since there is no
indication that the card is ready to accept commands.

This patch works around the problem by using the the TX Download Ready
bit in place of the Command Download Ready Bit while in IEEE PS mode.
TX Download Ready is set in IEEE PS mode.

When the hard state changes, we shouldn't set the soft
state to blocked as well -- we have no such indication
from the device in that case so leave it untouched.

When both MSI-X and legacy INTx fail to generate an interrupt, the

menuconfig IEEE802154_DRIVERS is a bool that depends on tristate IEEE802154.
If the IEEE802154 symbol is 'm', the bool becomes 'y'.
This allows tristate symbols under IEEE802154_DRIVERS to be configured as
'y' and cause build problems.
Changing the menuconfig bool to a tristate fixes this.

This patch fixes the clock setup in tmio_mmc.

  * Incorrect divider setting
  * Cruft written to the clock registers (seemingly harmless but Not
Good (tm))

It also eliminates some unnecessary ifs and tidies the loop syntax.

Thanks to Philipp Zabel who discovered the divider issue, commenting

   "Except for the SDCLK = HCLK (divider bypassed) case, the clock
    setting resulted in double the requested frequency.
    The smallest possible frequency (f_max/512) is configured with
    a divider setting 0x80, not 0x40."

A pointer to mmc_omap_probe which lives in .init.text is passed to the
core via platform_driver_register and so the kernel might oops if probe
is called after the init code is discarded.

As requested by David Brownell platform_driver_probe is used instead of
moving the probe function to .devinit.text.  This saves some memory, but
might have the downside that a device being registered after the call to
mmc_omap_init but before the init sections are discarded will not be
bound anymore to the driver.
