ata: sata_mv: enable SoC SATA LED presence indication

Browse Source 
Enable the SoC SATA LED controller in mv_soc_enable_leds().

Set the LED controller enable and device presence multiplexing bits
in the SoC SATA host-controller register. This enables SATA device
presence indication on boards using the SoC SATA controller.
