When WLAN is attached to PCIe switch, set and retrain DSP <-> EP link
in BW scale callback function. It avoids touching RC <-> USP link which
may impact other devices.
With this change, it could support Hamilton PCIe Gen3 on PCIe switch
platform.

CNSS driver controls the power on/off wlan device. because on CPE
platform the link/power status of RC<->USP may be still on when wlan
device is turning on/off, this may cause uncorrectable AER error on
DSP side, to avoid this issue DSP's downstream link should be
disabled before power on/off wlan device, and re-enabled after wlan
power on, and also wait for link training of DSP<->WLAN to complete.
To be compitable with non PCIE switch platform, add a new config
CONFIG_PCIE_SWITCH_SUPPORT to enable/disable this function

At the auto platform, DRV feature is not applicable.
So do not issue any DRV related operation from cnss2
side, which may cause the RC PHY not ready in the LPM
case.

Some platforms can't meet the number of MSI interrupt vectors that
wlan driver requires.
Add one MSI interrupt vector support.
If CONFIG_ONE_MSI_VECTOR is not defined, wlan driver fails to load
if reuired MSI vector allocation fails. It is current behavior.
If CONFIG_ONE_MSI_VECTOR is defined, firstly it will allocate multiple
MSI vectors based on MSI config. If MSI vector allocation fails, it
fallbacks to one MSI vector automatically.

Add code to move the platform related apis mainly defined under
CONFIG_ARCH_QCOM and CONFIG_PCI_MSM flags to separate file,
named pci_qcom.c. This change facilitates easy code upgrade for
customer.
