brcmfmac: handle FWHALT mailbox indication

Browse source

The firmware uses a mailbox to communicate to the host what is going
on. In the driver we validate the bit received. Various people seen
the following message:

 brcmfmac: brcmf_sdio_hostmail: Unknown mailbox data content: 0x40012

Bit 4 is cause of this message, but this actually indicates the firmware
has halted. Handle this bit by giving a more meaningful error message.
