[PATCH 02/03] ARM: mach-shmobile: sh7372 generic board support via DT

[Magnus Damm <magnus.damm@gmail.com>]

From: Magnus Damm <damm@opensource.se>

Add generic DT board support for the sh7372 SoC.

SCIF serial ports and timers are kept as regular
platform devices. Other on-chip and on-board devices
should be configured via the device tree.

Tested on the mackerel board via kexec using a zImage
kernel with an appended dtb.
