Subject: [PATCH net-next 05/10] net: ipa: share field mask values for GSI interrupt type

The GSI interrupt type register and interrupt type mask register
have the same field bits at the same locations.  Use a common set of
field masks for both registers rather than essentially duplicating
them.  The only place the interrupt mask register uses any of these
is in gsi_irq_enable().
