Additional Fixes for saa7134 suspend/resume
From: Maxim Levitsky <maximlevitsky@gmail.com>
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
