dt-bindings: ata: ahci-fsl-qoriq: add fsl,ls1046a-ahci and fsl,ls1012a-ahci

Add missing documented compatible strings 'fsl,ls1046a-ahci' and
'fsl,ls1012a-ahci'. Allow 'fsl,ls1012a-ahci' to fallback to
'fsl,ls1043a-ahci'.

Fix below CHECK_DTB warnings
arch/arm64/boot/dts/freescale/fsl-ls1012a-qds.dtb: sata@3200000:
compatible:0: 'fsl,ls1012a-ahci' is not one of ['fsl,ls1021a-ahci',
'fsl,ls1043a-ahci', 'fsl,ls1028a-ahci', 'fsl,ls1088a-ahci',
'fsl,ls2080a-ahci', 'fsl,lx2160a-ahci']

arch/arm64/boot/dts/freescale/fsl-ls1012a-qds.dtb: sata@3200000:
compatible: ['fsl,ls1012a-ahci', 'fsl,ls1043a-ahci'] is too long
