Replace open coded instances of FIELD_GET() with it, move register
definitions at the top of the file and also replace magic numbers
with register definitions.
While at it, also change a regmap_update_bits() call to regmap_write()
because the top 29 bits of AUD_TOP_CFG (31:3) are reserved (unused).

Shouldn't be unsigned too ?
I'm wondering if it would be better (probably in another patch) to
change the data type of the other variables too, to match their
use-case. (maybe it's already the case, I'm just wondering)
