ARM: SoC platform changes for 3.18 

New and updated SoC support. Among the things new for this release are:
 
 - at91: Added support for the new SAMA5D4 SoC, following the earlier SAMA5D3
 - bcm: Added support for BCM63XX family of DSL SoCs
 - hisi: Added support for HiP04 server-class SoC
 - meson: Initial support for the Amlogic Meson6 (aka 8726MX) platform
 - shmobile: added support for new r8a7794 (R-Car E2) automotive SoC
 
 Noteworthy changes to existing SoC support are:
 
 - imx: convert i.MX1 to device tree
 - omap: lots of power management work
 - omap: base support to enable moving to standard UART driver
 - shmobile: lots of progress for multiplatform support, still ongoing
