V4L/DVB (6329): Additional Fixes for saa7134 suspend/resume

Fixes few more problems I found in my saa7134 resume code:

* Race between IRQ handler and .suspend()/.resume() functions

* Removes timeout timers on active buffers - those
	buffers will be recaptured after resume

* Adds suspend/resume for IR code - probably
	necessary if using polling mode

* Adds #ifdef CONFIG_PM overs suspend code

* Runs  a quirk in set_tvnorm in suspend/resume too

* Rearranges the order of calls in saa7134_resume to
	be exactly as in saa7134_initdev thus the card is
	initialized in exactly the same way

* Since DMA audio capture suspend/resume isn't yet supported,
	avoid re-enabling it on resume for now
