[PATCH 374/379][SRU][OEM-5.6] ath11k: hif: add ce irq enable and disable functions

[You-Sheng Yang]

From: Carl Huang <cjhuang at codeaurora.org>

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

Add ce irq enable and disable hif layer functions, so core module can enable
enable them without cleaning pipe and refilling pipe. Needed for suspend.

Tested-on: QCA6390 hw2.0 PCI WLAN.HST.1.0.1-01740-QCAHSTSWPLZ_V2_TO_X86-1
