[PATCH 05/26][SRU][U/OEM-5.10] UBUNTU: SAUCE: ath11k: hook mhi suspend and resume

[You-Sheng Yang]

From: Carl Huang <cjhuang at codeaurora.org>

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

MHI suspend and resume isn't hooked in ath11k yet, so hook these
functions. Host also exposes functions for hif layer to call.

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