When we can't configure the dma channel we want to fall
back to PIO. We do this by setting host->do_dma to zero.
This does not work as do_dma is used to see whether dma
can be used for the current transfer. Instead, we have
to set host->dma to NULL.

This converts the remaining USB drivers in the kernel to use the

Added bonus is that it removes some unneeded kernel log messages about

In dw_mmc 2.40a spec, Data register's offset is changed.
Before we used Data register offset 0x100. but if somebody uses a
2.40a controller, we must use 0x200 for Data register.
This patch adds a version-id checking point and uses SDMMC_DATA(x)
instead of SDMMC_DATA. It assumes 2.40a is the latest version.

Go through the driver's set_power() functions rather than
calling regulator_enable/disable() directly because otherwise
pbias configuration for MMC1 is not done.

This patch adds support for the power off notify feature, available in
eMMC 4.5 devices. If the host has support for this feature, then the
mmc core will notify the device by setting the POWER_OFF_NOTIFICATION
byte in the extended csd register with a value of 1 (POWER_ON).
For suspend mode short timeout is used, whereas for the normal poweroff
long timeout is used.

Ths patch allows runtime PM for sdhci-pci, runtime suspending after
inactivity of 50ms and ensuring runtime resume before SDHC registers
are accessed. During runtime suspend, interrupts are masked.
The host controller state is restored at runtime resume.
For Medfield, the host controller's card detect mechanism is
supplanted by an always-on GPIO which provides for card detect wake-up.

Since commit [e58aa3d2: genirq: Run irq handlers with interrupts
disabled], we run all interrupt handlers with interrupts disabled
and we even check and yell when an interrupt handler returns with
interrupts enabled (see commit [b738a50a: genirq: Warn when handler
enables interrupts]).
So now this flag is a NOOP and can be removed.
