net: ipa: fix inter-EE IRQ register definitions
In gsi_irq_setup(), two registers are written with the intention of
disabling inter-EE channel and event IRQs.
But the wrong registers are used (and defined); the ones used are
read-only registers that indicate whether the interrupt condition is
present.
Define the mask registers instead of the status registers, and use
them to disable the inter-EE interrupt types.
Fixes: 46f748ccaf01 ("net: ipa: explicitly disallow inter-EE interrupts")
