Added a new config CONFIG_SATA_ZPODD, which is used to support SATA based zero power ODD. It depends on ATA_ACPI, and selects BLK_DEV_SR as the implementation of ZPODD depends on SCSI sr driver. A new file libata-zpodd.c is added, which will be used to host ZPODD related code. It is empty for this commit.
