net: ipa: share field mask values for IPA hash registers
The IPA filter/routing hash enable register and filter/routing hash
flush register each have four single-bit fields representing the
four hashed tables to be enabled or flushed. The field positions
are identical, so just use a single set of field masks to represent
the fields for both registers.
