Subject: [PATCH] brcmfmac: introduce brcmf_fw_alloc_request() function
The function brcmf_fw_alloc_request() takes a list of required files
and allocated the struct brcmf_fw_request instance accordingly. The
request can be modified by the caller before being passed to the
brcmf_fw_request_firmwares() function.

Subject: [PATCH] brcmfmac: add extension to .get_fwname() callbacks
This changes the bus layer api by having the caller provide an
extension. With this the callback can use brcmf_fw_alloc_request()
to get the needed firmware name.
