wifi: brcmfmac: keep power during suspend if board requires it
After commit 92cadedd9d5f ("brcmfmac: Avoid keeping power to SDIO card
unless WOWL is used"), the wifi adapter by default is turned off on
suspend and then re-probed on resume.
This conflicts with some embedded boards that require to remain powered.
They will fail on resume with:
brcmfmac: brcmf_sdio_bus_rxctl: resumed on timeout
ieee80211 phy1: brcmf_bus_started: failed: -110
ieee80211 phy1: brcmf_attach: dongle is not responding: err=-110
brcmfmac: brcmf_sdio_firmware_callback: brcmf_attach failed
This commit checks for the Device Tree property 'cap-power-off-cards'.
If this property is not set, it means that we do not have the capability
to power off and should therefore remain powered.
