[PATCH V2 4/5] ata: ahci_platform: Add synopsys ahci controller in DT's compatible list

[Viresh Kumar <viresh.linux@gmail.com>]

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.
