net: ipa: define GSI interrupt types with an enum
Define the GSI interrupt types with an enumerated type whose values
are the bit positions representing each interrupt type. Include a
short comment describing how each interrupt type is used.
Build up the enabled interrupt mask explicitly in gsi_irq_enable(),
and get rid of the definition of GSI_CNTXT_TYPE_IRQ_MSK_ALL.
