ata: ahci_platform: Add ACPI _CLS matching
This patch adds ACPI supports for AHCI platform driver, which uses _CLS
method to match the device.
The following is an example of ASL structure in DSDT for a SATA controller,
which contains _CLS package to be matched by the ahci_platform driver:
Device (AHC0) // AHCI Controller
{
Name(_HID, "AMDI0600")
Name (_CCA, 1)
Name (_CLS, Package (3)
{
0x01, // Base Class: Mass Storage
0x06, // Sub-Class: serial ATA
0x01, // Interface: AHCI
})
Name (_CRS, ResourceTemplate ()
{
Memory32Fixed (ReadWrite, 0xE0300000, 0x00010000)
Interrupt (ResourceConsumer, Level, ActiveHigh, Exclusive,,,) { 387 }
})
}
Also, since ATA driver should not require PCI support for ATA_ACPI,
this patch removes dependency in the driver/ata/Kconfig.
