[OE-core] [RFC 3/3] linux-firmware: MACHINEOVERRIDES for BCM43430 NVRAM

[Ryan Harkin]

The Linux kernel currently expects a single NVRAM file for BCM43430
named brcmfmac43430-sdio.txt.

Allow the machine to specify an override to link its module specific
NVRAM to the filename expected by the kernel.
