Subject: [PATCH v3 1/3] ata: ahci_platform: Update DT compatible list

The ahci_platform driver supports "snps,exynos5440-ahci" and
"ibm,476gtr-ahci". Add this to the DT binding information.

Also add compatible string "snps,dwc-ahci", which should be used
for Synopsis Designware SATA cores. e.g. on TI OMAP5 and DRA7 platforms.
