Add and initialize a preallocated pool of buffers which can
be used to replenish RX buffers. During replenish, the buffers
from the pool are used instead of allocating/mapping a new buffer
in the softirq context. This preallocated pool will be refilled
in thread context.

The memory below 0x2000 is reserved for the target use,
so any memory in this region should not used by host.
But on some third-party platforms, we observe such
memory is allocated for RX buffer, which cause HW/FW
NOC error, then RX is stuck. To address this,
re-allocate RX buffers when small buffer appear.

Currently the FW configures the mac with appropriate
offsets for rx pkt tlvs using the structure defined in

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.

When runtime power management is enabled, until the system is fully
resumed, we do not post any message to CE, instead they will be queued
in HTC. Once the device is fully resumed, all HTT messages in the queues
will be downloaded to CE at once. In some corner cases, it is found that
too many FSE caches flush messages getting queued during the runtime
resume; once the device is fully resumed, all these would be downloaded
to the FW/HW at once causing unintended crashes.
Avoid posting FSE cache flush messages until the device is fully resumed
to fix the issue.
