A previous changes which added the newer model HVR-1600's and DTV support for
them, neglected to add RF analog TV for them.  Fix RF analog TV for the newer
HVR-1600's which have a worldwide analog tuner assembly with a TDA18271 tuner
and TDA8295 demodulator.

Thanks go to Jeff Campbell and Mike Bradley for reproting the problem, and
also to Mike Bradley for doing a lot of the legwork to figure out the tuner
reset GPIO line, the demodulator I2C address, and that the GPIOs have to be
reinitialized after a cardtype switch.

The macro is defined as:

This sucks, as makes harder to debug if something got wrong and
there are more than one level of loops. Also, violates CodingStyle.

Fixed by this simple perl script:

	while (<>) { $f.=$_; };

	$f=~ s,\n\#define CHK_ERROR[^\n]+\n,\n,;

	$f=~ s=(CHK_ERROR\(.*\,)\n\s+=\1 =g;

This file is big. It has 12000+ lines! Most of the defined stuff aren't
used anyware inside the driver, so we can just remove most of the lines
and still keep everything that have any interest for the driver.

If anyone ever need the other devices, it will be stored at git logs, so
it is easy to recover.

The diff result is impressive:
 1 files changed, 1013 insertions(+), 12694 deletions(-)
 rewrite drivers/media/dvb/frontends/drxd_map_firm.h (90%)

As a sideback effect, drxd driver will likely compile faster, and
checkpatch.pl can run on this file without taking (literally) hours.

The code cleanup was done using this small script:
	$ for i in `perl -ne 'print "$1\n" if (m/define\s+([^\s+]+)/)' drxd_map_firm.h`; do if [ "`grep $i drivers/media/dvb/frontends/drxd*.[ch]`" != "" ] ; then echo $i; fi; done|sort|uniq >used_symbols
	$ grep -f used_symbols drxd_map_firm.h >defines

And then deleting the old #define lines, replacing by "defines" file content.

The em28xx bridge strobes the reset pin on the drx-d on every ts_ctrl call.
This results in the state of the chip getting out of the sync with the
state of the driver (and hence all tuning requests after the first one fail).

Make sure the drx-d is not being held in reset, but don't actually perform a
hardware reset on the chip.

The GPIO block has been split out from the other HVR-9x0 variants to reduce
the risk of regression, although in theory they would not have any issues
since none of those cases have the frontend driver managing any internal
state.

  MIPS: RB532: Fix iomap resource size miscalculation.

Commit b826291c, "drivercore/dt: add a match table pointer to struct
device" added an of_match pointer to struct device to cache the
of_match_table entry discovered at driver match time.  This was unsafe
because matching is not an atomic operation with probing a driver.  If
two or more drivers are attempted to be matched to a driver at the
same time, then the cached matching entry pointer could get
overwritten.

This patch reverts the of_match cache pointer and reworks all users to
call of_match_device() directly instead.

If two drivers are probing devices at the same time, both will write
their match table result to the dev->of_match cache at the same time.

Only write the result if the device matches.

In a thread titled "SBus devices sometimes detected, sometimes not",
Meelis reported his SBus hme was not detected about 50% of the time.
From the debug suggested by Grant it was obvious another driver matched
some devices between the call to match the hme and the hme discovery
failling.
