armv8: LS2080A: Rename LS2085A to reflect LS2080A

LS2080A is a prime personality of Freescale’s LS2085A. It is a non-AIOP
personality without support of DP-DDR, L2 switch, 1588, PCIe endpoint etc.
So renaming existing LS2085A code base to reflect LS2080A (Prime personality)

+/* Stream IDs on ls2080a devices are not hardwired and are
+ * programmed by sw.  There are a limited number of stream IDs
+ * available, and the partitioning of them is scenario dependent.
+ * This header defines the partitioning between legacy, PCI,
+ * and DPAA2 devices.
+ *
+ * This partitiong can be customized in this file depending
+ * on the specific hardware config-- e.g. perhaps not all
+ * PEX controllers are in use.
+ *
+ * On LS2080 stream IDs are programmed in AMQ registers (32-bits) for
+ * each of the different bus masters.  The relationship between
+ * the AMQ registers and stream IDs is defined in the table below:
+ *          AMQ bit    streamID bit
