Merge tag 'aspeed-5.8-devicetree' of git://git.kernel.org/pub/scm/linux/kernel/git/joel/aspeed into arm/dt

ASPEED device tree updates for 5.8

New machines:

 - YADRO's ast2500 OpenPower P9 Nicole BMC
 - Facebook's ast2500 x86 Yosemite V2 BMC

The AST2600 machines Rainier and Tacoma were fleshed out.

Machines have started describing the GPIO names as userspace attempts
to use the GPIO chardev API.
