It's a NOOP since 2.6.35 and it will be removed one day.
This is not trivial because current code uses hard coded 32 instead of
IRQF_DISABLED in the request_irq call.

For MMC_BUS_WIDTH_8 case, current code missed setting BM_EIGHTBIT_MODE bit.
Also has a small refactor to make the code looks better in readability.
So the bit settings witch below logic:
SDMMC_BUSMODE register:
Set EIGHTBIT_MODE bit for 8 bit mode, Set FOURBIT_MODE bit for 4 bit mode.
Clear both EIGHTBIT_MODE and FOURBIT_MODE bits for 1 bit mode.
SDMMC_EXTCTRL register:
Set EXT_EIGHTBIT bit for 8 bit mode, Clear EXT_EIGHTBIT bit for 1/4 bit mode.
Add define for EXT_EIGHTBIT to avoid using magic number.
BM_ONEBIT_MASK is no longer used, thus remove it.
This patch is untested due to lack of platform with 8-bit hardware.
However since the code is there, it's good to make the code match the document.

Suspend and resume of cards are being handled from the protocol layer
and consequently the mmc_suspend|resume_host APIs are deprecated.
This means we can simplify the suspend|resume callbacks by removing the
use of the deprecated APIs.

With the __devinit/__devexit attributes having been removed, this
__exitp attribute causes an unused function warning and should be
removed as well.

This patch adds support for the SD/MMC host controller found
on Wondermedia 8xxx series SoCs, currently supported under
arm/arch-vt8500.
A binding document is also included, based on mmc.txt with
additional properties.
