brcmfmac: Reset PCIE devices after recognition.

Browse source

When PCIE type devices are being FW reloaded without being properly
reset then the device ends up in a locked state, requiring the
device to be completely powered down. This patch adds a reset
through watchdog at the moment the device (cores) has been
recognized. This will solve warm reboot issues.
