This patch series starts by collecting a patch sent from Dan in the past
which improves the HW slot programming on V2H(P) to avoid losing frames
under heavy system load conditions.

Tommaso also sent a series a few months ago for the CRU from which I
collected the first two patches.

Around it, I've reworked a bit the locking in the driver which is a bit
coarse and causes lost of frames under heavy system load conditions.

Along with these, bit of drive-by cometic changes here and there to
modernize the driver code.

I've tested on V2H(P) but I've also modified the G2L IRQ handler, so if
anyone could test on G2L and G3E it would be great!
