Subject: [PATCH] ahci_qoriq: bug fix for ecc_addr
Original driver expect a register node with name "sata-ecc"
this node is of 64 bit wide.
In ACPI such nodes can be provided with QWordMemory, but
QWordMemory can not hold DescriptorName more than 4 characters.
Therefore this patch changes platform property retrival based
upon index instead of named.
