cnss2: Force PM resume for qca6390

For whatever reason, the qca6390 is not in M3 state
during PM resume phase, but still functional if do
force resume. So calling mhi_pm_resume_force()
instead of the mhi_pm_resume() to unblock PM
resume for kernel 5.15.

As for lower kernel version, like 5.4, it will do local
mhi pm state check in the mhi_pm_resume() instead of
target pm state check, so has no issue with qca6390.
