Each GSI channel has a CNTXT_1 register that encodes the size of its
ring buffer. The size of the field that records that is increased
starting at IPA v4.9. Replace the use of a fixed-size field mask
with a new inline function that encodes that size value.
Similarly, the size of GSI event rings can be larger starting with
IPA v4.9, so create a function to encode that as well.
