In epping mode, the host ce count is not set correctly. And
then host will receive interrupt with incorrect ce id which
will trigger watchdog bite. Set the correct host ce count
and this issue can be fixed.

Any update to the SRNG TP/HP when the device is in low power
state would result in system errors. It is recommended to disable
EXT grp irqs and drain TXRX before sending power save enter command
to the FW. This will ensure that no interrupts are received while
in power save mode and as a result there wont be any HP/TP updates.

Issue1: Driver RTPM state is ON/NONE, Kernel state is RESUMING.
cdp_runtime_resume is already complete,
hif_pm_runtime_get return -E_INPROGRESS,
dp_tx_hw_enqueue will set the flush event,
but cdp_runtime_resume is already done,
this flush event will be handled only on next pkt tx.
Issue2: Driver RTPM state: Resuming
hif_pm_runtime_get returns -EBUSY,
dp_tx_hw_enqueue is interrupted by any IRQ,
cdp_runtime_resume is completed,
dp_tx_hw_enqueue will set the flush event,
This flush event will be handled only on next pkt tx.
Fix:
Introduce a link_state_up atomic variable in hif to track the link state
change by pld_cb.
Set atomic variable link_state_up=1 in pmo_core_psoc_bus_runtime_resume
just after pld_cb. pld_cb brings the PCIe bus out of suspend state.
Set atomic variable link_state_up=0 in pmo_core_psoc_bus_runtime_suspend
just before pld_cb. pld_cb puts the PCIe bus into suspend state.
Introduce dp_runtime_get and dp_runtime_put.
dp_runtime_get get refcount with increment of an atomic variable.
dp_runtime_put return refcount with decrement of this atomic variable.
If hif_pm_runtime_get returns -EBUSY or -EINPROGRESS,
take the dp runtime refcount using dp_runtime_get,
check if the link state is up, write TX ring HP,
return the dp runtime refcount using dp_runtime_put.
cdp_runtime_suspend should reject the suspend, if dp_runtime_get is non
zero.
cdp_runtime_resume should wait until dp_runtime_get becomes zero or time
out, then flush pending tx for runtime suspend.

Currently if the driver is in runtime suspend/suspending
state, any packet transmission will request for resume
via hif_pm_runtime_get.
Unfortunately there is a logging in the above API which
will lead to more time consumption in the NET_TX softirq
context. This can lead to other delay in processing other
softirqs in the system.
Fix this by skipping the logging in the packet transmission
path.

Issue happens when
step 1: kernel pm core start to runtime suspend
step 2: host get wma_acquire_wakelock & send PDEV_SET_HW_MODE.
step 3: host send wow_enable cmd
step 4: wow suspend finished and wow resume happens as step2
send pm_runtime_get
step 5: fw dop PDEV_SET_HW_MODE as enter wow mode
so host can't get PDEV_SET_HW_MODE_RESP from fw.
Fix is:
Don't allow suspend if sending PDEV_SET_HW_MODE.
After change logical will be:
1 if PDEV_SET_HW_MODE before send hif_pre_runtime_suspend->
hif_runtime_pm_set_state_suspending, then wow suspend
will return failure.
2 if PDEV_SET_HW_MODE send after hif_pre_runtime_suspend->
hif_runtime_pm_set_state_suspending, it will request resume

Currently DMA mask for the device is set during hif_enable_bus.
If the datapath memory prealloc feature is enabled, there are
a few dma memory allocation which is done before the DMA mask
is set for the device. This leads to the aforementioned dma
memory pre-allocation to be attempted at the default DMA mask.
Due to this the entire device capability of dma address might
not be used.
Add hif api to set dma mask before hif is initialized. This
is needed to set dma mask in case of datapath memory pre allocation.
