For specific QCA6174 device, need clear LOW_POWER_INT_MASK register
bit3/4 to disable pcie low power interrupt after suspend, bit3 is for
INTR_L1SS and bit4 is for INTR_CLKPM, this is to fix issue that PMIC
VREG_L30A don't turn off when XO is in shutdown state.

Remove logic to enable/disable wake msi for drv systems. Today, during
WoW suspend sequence, between hif pci bus suspend and hif pci bus
suspend no irq, wake msi is getting disable temporarily. In case
fw toggles wake msi during this period, then the wake msi is lost,
which can lead to device not waking up for fw triggered wakeup.
Add the fix to remove enable/disable wake msi from suspend/resume
path and keep wake msi always enabled.

Currently sleep based wait is used for checking EP request/release
vote is taken effect or not. But once worker thread goes to sleep
it is taking in order of milli seconds to schedule back worker thread
this scheduling delay is causing srng HP/TP writes to be updated in
delayed manner.
To avoid this first try checking EP vote is taken affect by busy wait
then go for sleep based method.

Runtime put should be done in hif_pm_runtime_get when
return value of __hif_pm_runtime_get is negative. In
the issue scenario, the ret value will be set to 0 when
the return value of __hif_pm_runtime_get is positive.
The store operation for ret variable somehow did not take
effect and the if check for non-zero ret value to do
runtime put did go through. The return value to
dp_tx_hw_enqueue from hif_pm_runtime_get is the updated
ret value of 0. This will result in double runtime put
for a single runtime get.
Fix is to modify the ret variable check to negative
instead of non-zero to ensure runtime put happens
correctly.
