[3/3] ARM: mach-shmobile: r8a7740: Setup the serial devices using DT

Commit Message

Bastian Hecht Feb. 19, 2013, 6:29 p.m. UTC

We can now use the Device Tree for bringing up our serial devices. We
need to add an alternative early_devices list in setup-r8a7740 without
the serial devices and move them into the Armadillo-reference .dts config file.
