This patch fixes the warning "Using plain integer as NULL pointer",
generated by sparse, by replacing
if (var == 0)
with
if (!var)
after an allocation
and all other offending 0s with NULL.

According with CodingStyle, drivers shouldn't use typedef, except on very
special cases. This is not the case of saa7164. So, convert all usecases
to struct/enum.
After changing the saa7164-types.h, all we need to do is to run those scripts
to fix all occurrences of the bad types and double check/fix everything that
might be broken after the test (of course, I did a small script to generate those scripts).

Which is why I have always preferred sizeof(struct foo) over
sizeof(var).

-tip testing found that the x86 build (64-bit allyesconfig) fails due to:
LD vmlinux.o
drivers/built-in.o:(.bss+0x4b648): multiple definition of `debug'
arch/x86/built-in.o:(.kprobes.text+0x88): first defined here
ld: Warning: size of symbol `debug' changed from 90 in
arch/x86/built-in.o to 4 in drivers/built-in.o
make: *** [vmlinux.o] Error 1
This is because recent saa7164 changes introduced a global symbol
named 'debug'. The x86 platform code already defines a 'debug'
symbol. (which is named in a too generic way as well - but it
can be used nicely to weed out too generic symbols in drivers ;-)
Rename it to saa_debug.

In some cases we're seeing large timeouts on commands. I'm changing the
implementation so that the deferred worker checks the PCI bus for
any messages and signals the waiting caller accordingly. The previous
mechanism was too unreliable.

The firmware typically responds in < 50ms and, via the interrupts and
deferred work queue the caller (blocked in the driver) is signalled very
efficiently. In a highly stressed system this can take many multiples
of seconds. So, we need a larger maximum timeout for busy systems.

This patch adds support for all of the known shipping Hauppauge HVR-2200
and HVR-2250 boards. Digital TV ATSC/QAM and DVB-T is enabled at this
time. Both tuners are supported.
Volatiles and typedefs need rework, the rest is coding style compliant.
