Currently Host driver calls cnss_force_collect_rddm API
to trigger RDDM and wait for dump collection. If device
fails to move to RDDM, CNSS driver initiate DEFAULT recovery
(which is recovery without RDDM dump collection) and return
failure to Host driver. Host driver sees error and again try
recovery which results in double recovery.
To avoid this issue, return success to Host driver if
CNSS driver has already initiated the DEFAULT recovery
and release rddm_complete wait event for DEFAULT recovery
cases also.

Remove unwanted delay from PCIe link down recovery sequence
1. Wait for wake event from PCIe driver instead of hardcoded wait.
2. After link recovers, wait for device to move to RDDM mode
instead of starting rddm timer.
3. If device fails to move to RDDM, assert HOST SOL and initiate
side band recovery.

There is known pcie linkdown issue for qca6490 if gen3 speed is used.
Previous solution is to downgrade to gen2 before enumeration, but it
doesn't work if platform support multiple wlan chips where device id
can't be determined until enumeration success.
The fix is:
1, Enumerate all devices with gen1 speed
2, When enumeration done, restore to gen2 if device is qca6490

To avoid this issue, should use disable_irq_nosync(), which doesn't
wait IRQ handler to finish. It should introduce no side effect, as
the whole device will be restated later by SSR.

With VT-d disabled on x86 platform, only one pci irq vector is allocated.
Due to the irq is not freed when suspend, the kernel will migrate irq to
CPU0 if it was affine to other CPU and then allocate a new MSI vector,
which cause the issue about no irq handler for vector once resume since
the driver only configure MSI data once during driver loading.
The fix is to set irq vector affinity to CPU0 before calling request_irq
to avoid the irq migration.

Some platform PCIe RC impedance can't achieve the target defined in spec.
It will result to Genoa card link down. To WA the issue, downgrade RC speed
to Gen1 for auto Genoa EP. Because the linkdown issue may happen during
enum, and before enumunation we do not know EP device ID, so set init
speed to Gen1, and then restore speed to default for others wifi chip.
The change does not affect Genoa throughput, because Gen1 speed is enough
for Genoa.
