wireless-drivers-next patches for v5.15 

First set of patches for v5.15. This got delayed as I have been mostly
 offline for the last few weeks. The biggest change is removal of
 prism54 driver, otherwise just smaller changes.
 
 Major changes:
 
 ath5k, ath9k, ath10k, ath11k:
 
 * switch from 'pci_' to 'dma_' API
 
 brcmfmac
 
 * allow per-board firmware binaries
 
 * add support 43752 SDIO device
 
 prism54
 
 * remove the obsoleted driver, everyone should be using p54 driver instead

This enables support for FullMAC PCI/Cardbus prism54 devices. This
driver is now deprecated in favor for the SoftMAC driver, p54pci.
p54pci supports FullMAC PCI/Cardbus devices as well.
For more information refer to the p54 wiki:
http://wireless.wiki.kernel.org/en/users/Drivers/p54
Note: You need a motherboard with DMA support to use any of these cards
When built as module you get the module prism54
