libertas: fix power save issue in libertas_sdio module

Browse source

The problem: "iwconfig ethX power on" returns error

The cause: "ps_supported" flag was never set for SD8385/8686

The fix: check firmware capabilities returned by GET_HW_SPEC command.
Set "ps_supported" to 1 if FW_CAPINFO_PS bit is on. This fix applies
to SDIO interface only.
