Subject: [PATCH v3 3/3] ata: ahci: Rename CONFIG_SATA_LPM_MOBILE_POLICY configuration item

`CONFIG_SATA_LPM_MOBILE_POLICY` reflects a configuration to apply only to
mobile chipsets.  As some desktop boards may want to use this policy by
default as well, rename the configuration item to `SATA_LPM_POLICY`.
