wifi: ath11k: implement CE interrupt enable/disable for AHB

Browse source

ath11k_core_reset() calls ath11k_hif_ce_irq_disable() right before it
powers the target down, but ath11k_ahb_hif_ops_ipq8074 never set the
ce_irq_enable/ce_irq_disable pair, and ath11k_hif_ce_irq_disable() does
nothing when the op is NULL. On AHB the copy engine interrupts and their
tasklets therefore stay live across rproc_shutdown(), where the register
space they touch is no longer accessible.

Wire the ops up. The sequence is the one ath11k_ahb_stop() already runs,
factored into a helper and reused, so behaviour on the stop path is
unchanged. wcn6750 is not affected: it uses the pcic ops, which
implement the pair already.
