net: ipa: share field mask values for GSI general interrupt
The GSI general interrupt is managed by three registers: enable; status; and clear. The three registers have same set of field bits at the same locations. Use a common set of field masks for all three registers to avoid duplication. Signed-off-by: Alex Elder <elder@linaro.org> Signed-off-by: David S. Miller <davem@davemloft.net>
