Subject: [PATCH RFC 05/16] ARM: dts: aspeed: Remove unspecified LPC host
 controller node

For the AST2500 the node was used for pinctrl purposes, and while the
hardware capability is also present in the AST2400 and AST2600, the
their pinctrl no relationship to it. Further, there's no corresponding
binding, remove the node for now to
eliminate the warnings.
