qcacld-2.0: Add platform driver based driver registration
To manage the power and suspend/resume sequences properly in MSM target,
the WLAN driver is registered to a platform driver instead of registering
as PCI device driver with the kernel. The platform driver registers
with kernel as a PCI device driver on behalf of WLAN driver.
It is responsible for controlling 3.3V, WLAN_EN GPIO and PCIe link
dynamically when WLAN driver is turned ON or OFF. The probe, remove,
suspend and remove callbacks are piggy backed to the WLAN driver from the
platform driver.
