Add UART routing driver and the device tree nodes.

v4:
 - Convert aspeed-lpc bindings to YAML schema to resolve dependecy issues

v3:
 - Add individual bindings in YAML
 - Add support for AST24xx (AST25xx shares the same design)
 - Add more explanation for the sysfs ABI

v2:
 - Add dt-bindings
 - Add ABI documents for the exported sysfs interface
 - Revise driver implementation suggested by Joel

Chia-Wei Wang (4):
  dt-bindings: mfd: aspeed-lpc: Convert to YAML schema
  dt-bindings: aspeed: Add UART routing controller
  soc: aspeed: Add UART routing support
  ARM: dts: aspeed: Add uart routing to device tree
