This register field is 11 bits wide, not 15 bits wide. Given the way
this value is currently, used, this patch has no practical effect.
However, it's still best if the value is correct.

Stop open-coding the caching of the ctrl registers; instead, use
regmap_update_bits() to update parts of the register from different
places. The removal of the open-coded cache will allow controls to be
created which touch registers, which will be necessary if any of these
modules are converted to CODECs.

Get rid of tegra*_read/write; just call regmap_read/write directly.
