[PATCH 1/2] soc: qcom: geni-se: Split IRQ status clearing from mode selection

[Viken Dadhaniya]

geni_se_irq_clear() both clears pending interrupt status and updates
mode-dependent event and IRQ enables. Split out the status-only operation
so cached mode selections can discard stale transfer completion status
without disabling GSI event routing.

No functional change.
