brcmfmac: sdio: Increase the default timeouts a bit
On a Radxa Rock2 board with a Ampak AP6335 (Broadcom 4339 core) it seems the card responds very quickly most of the time, unfortunately during initialisation it sometimes seems to take just a bit over 2 seconds to respond. This results intialization failing with message like: brcmf_c_preinit_dcmds: Retreiving cur_etheraddr failed, -52 brcmf_bus_start: failed: -52 brcmf_sdio_firmware_callback: dongle is not responding Increasing the timeout to allow for a bit more headroom allows the card to initialize reliably. A quick search online after diagnosing/fixing this showed that Google has a similar patch in their ChromeOS tree, so this doesn't seem specific to the board I'm using.
