powerpc: Add a vga alias node for P1022
In u-boot, when set the video as console, the name 'vga' is used as a general name for the video device, during the fdt_fixup_stdout process, the 'vga' name is used to search in the dtb to setup the 'linux,stdout-path' node. Though the P1022 DIU is not VGA-compatible device, to meet the 'vga' name used in u-boot, the vga alias node is added for P1022 in this patch. At the same time, a display alias is also added so that no other components grow dependencies on the vga alias node.
