qcacmn: Cleanup snoc interrupt controll

Remove interupt enable/disable at group level since
in register set 81, these registers are not provided.
Don't enable/disable the ce irqs at the qgic
since the interrupts are edge driven, enabling and disabling the interrupt
in the qgic should not be necessary.  Also remove an unneeded read
of a status register.
