Merge tag 'aspeed-4.12-devicetree' of git://git.kernel.org/pub/scm/linux/kernel/git/joel/aspeed into next/dt

Aspeed devicetree updates for 4.12

Updates to the device tree to include upstreamed drivers:

 - SPI flash controller
 - Watchdog
 - ADC

In addition we describe some of the clocks so that upstream kernels can
boot on hardware.
