Proper handling of suspend/resume in the wbsd driver.

In PM v1, all devices were called at SUSPEND_DISABLE level. Then
all devices were called at SUSPEND_SAVE_STATE level, and finally
SUSPEND_POWER_DOWN level. However, with PM v2, to maintain
compatibility for platform devices, I arranged for the PM v2
suspend/resume callbacks to call the old PM v1 suspend/resume
callbacks three times with each level in order so that existing
drivers continued to work.
Since this is obsolete infrastructure which is no longer necessary,
we can remove it. Here's an (untested) patch to do exactly that.

The wbsd driver's card detection routing is a bit of a mess. This
patch cleans up the routine and makes it a bit more comprihensible.

Clean out trailing whitespace caused by not-so-great editor since it
generates a lot of problems with editors configured to automatically
strip whitespace.

Convert wbsd to use the new delay functionality in mmc_detect_change()
rather than implementing its own timer.

Change mmc_detect_change() to take a delay argument such that
the detection of card insertions and removals can be delayed
according to the requirements of the host driver or platform.

Even though the changes are minor for the next release an increasing
version number simplifies my support issues.

`gcc -W' likes to complain if the static keyword is not at the beginning of
the declaration. This patch fixes all remaining occurrences of "inline
static" up with "static inline" in the entire kernel tree (140 occurrences in
47 files).
While making this change I came across a few lines with trailing whitespace
that I also fixed up, I have also added or removed a blank line or two here
and there, but there are no functional changes in the patch.

This patch contains the following possible cleanups:
- make some needlessly global code static
- remove the unneeded global function DBG_REG

Wait 0.5 seconds before scanning for cards after an insertion interrupt.
The electrical connection needs this time to stabilise for some cards.

Updates to the wbsd driver.
* Fix to handle DAT3 card detection.
* Fixed bug which could cause large writes to stall in FIFO mode.
* Plug 'n Play support. In most cases you need ACPI PNP for this to work.
* Uses generic DMA API (ISA dependency removed).
This fixes u32 vs. pm_message_t in drivers/mmc, drivers/mtd and
drivers/scsi.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
