mwifiex: add PCIe8897 support 

This patch adds PCIe8897 support to mwifiex.
In PCIe8897 PFU (pre-fetch unit) is enabled by default.
This patch adds support to accommodate this feaure as well.

This adds support for wireless adapters based on Marvell
8766 chipset with PCIe interface.
8766/8897 chipsets with PCIe interface.
If you choose to build it as a module, it will be called
