brcmfmac: add 43752 SDIO ids and initialization

Add HW and SDIO ids for use with the SparkLan AP6275S
Add the firmware mapping structures for the BRCM43752 chipset.
The 43752 needs some things setup similar to the 43012 chipset.
The WATERMARK shows better performance when initialized to the 4373 value.
