Viresh Kumar [Sat, 21 Apr 2012 12:10:12 +0000 (17:10 +0530)]
SPEAr13xx series of SoCs contain Synopsys AHCI SATA Controller which shares
ahci_platform driver with other controller versions.

This patch updates DT compatible list for ahci_platform. It also updates and
renames binding documentation to more generic name.
