cnss: Enable cnss_msm_pcie_pm_control

In order to support WLAN SSR in GVM, we need to enable
PCIe suspend/resume. PCIe suspend/resume requires ldo
reset. GVM has no direct control to PCIe ldos,instead,
they are managed in ghs hypervisor. During WLAN SSR,
GVM will send out power messages to ghs via subsystem
SSR framework which will reset WLAN/PCIe ldos accordingly.

Suspend/resume set is skipped during registration/
un-registration because GVM is not able to inform ghs
to do ldo operations in such scenarios. And if PCIe link is
suspended upon registration, it can resume no more.
