Subject: [PATCH] NXP/LX2160A/AcpiTables: Sata add Class code for generic AHCI
 support

Add this class code so AHCI functions properly on kernels that don't
have the qoriq specific AHCI driver.

This still misses the quirk for V1 silicon that if the device is hard
reset the SerDes can lose link, but in general this is enough to boot
and install an OS.
