net: ipa: fix BCR register field definitions
The backward compatibility register field masks are defined using
single-bit masks defined with BIT(x) rather than GENMASK(x, x).
Change this one set of definitions to follow the GENMASK() pattern
used everywhere else. Add a few missing field definitions for this
register as well.
