This patch removes the remaining defines that are already defined
identically in the sis initdef.h header.

Since the defines TVVCLKDIV2, TVVCLK, HiTVVCLKDIV2, HiTVVCLK,
HiTVSimuVCLK and HiTVTextVCLK are now defined as relative values, we
have to use TVCLKBASE_315 (0x31) as a base address to get the same values
as before the merge.

This patch renames some of the defines that exist in the sis initdef.h
but seem to have a different value.
In order to preserve the functionality of the driver, we simply prepend
these defines with XGI_ (for now) to resolve conflicts and review them
later on.
Renames:
SetCRT2ToLCDA -> XGI_SetCRT2ToLCDA

This patch includes the initdef.h header from the sis driver.
Since the xgi driver used to redefine a lot of stuff from the sis
driver, we can simply include the headers of the sis driver itself, so
we can remove duplicated stuff later on.
In order to include the initdef.h we have to rename the header guards.

Big things here is the deletion of the Android pmem driver, as it's
obsolete and no one uses it, the gma500 driver as it's already in the
drm portion of the kernel tree, and the pohmelfs filesystem as it's
obsolete and a rewritten version is being proposed for the fs/ section
of the kernel.
Other than that, a smattering of different bugfixes and regressions, and
some omap drm api merge fixups that were needed due to api changes in
the main portion of the drm tree, allowing this code to build properly
again.

_parse_integer() does one or two division instructions (which are slow)
per digit parsed to perform the overflow check.
Furthermore, these are particularly expensive examples of division
instruction as the number of clock cycles required to complete them may
go up with the position of the most significant set bit in the dividend:
if (*res > div_u64(ULLONG_MAX - val, base))
which is as maximal as possible.
Worse, on 32-bit arches, more than one of these division instructions
may be required per digit.
So, assuming we don't support a base of more than 16, skip the check if the
top nibble of the result is not set at this point.

Neither of these drivers has ever been anywhere near the iio abi.
Probably as a result of this the fact they had two event groups
each was not picked up when we restricted IIO to having only
1 event line per device (as part of the chrdev merge set).
As such these definitely didn't work before. This patch squishes
the only element from the 'comparator' event line that isn't in the
'interrupt' one into it and kills off the 'comparator' one.
Ultimately both of these drivers belong in hwmon not IIO and are just
waiting here because I don't want to kill off a driver that may
prove useful to someone. (Ultimately I will ask Greg to scrap
these two if no one steps up to deal with them.)

We always hold the waitqueue lock when modifying the flags field. So it is safe
to use the non-atomic bitops here instead of the atomic versions.

The core iio file has gotten quite cluttered over time. This patch moves
the event handling code into its own file. Since the event handling code is
largely independent from the core code the only code changes necessary for
this are to make the moved iio_device_register_eventset,
iio_device_unregister_eventset and iio_event_getfd functions non static.
This has also the advantage that industrialio-core.c is now closer again to
its counterpart in the outofstaging branch.
