[PATCH 079/379][SRU][OEM-5.6] ath11k: set IRQ_DISABLE_UNLAZY flag for DP interrupts

[You-Sheng Yang]

From: Manikanta Pubbisetty <mpubbise at codeaurora.org>

BugLink: https://bugs.launchpad.net/bugs/1879633

Unlike CE interrupts, DP interrupts are not enabled/disabled at
source; they are enabled/disabled only at GIC level, therefore
it is required to set IRQ_DISABLE_UNLAZY flag to avoid spurious
interrupts.
