This patch adds support for MCP454x, MCP456x, MCP464x and MCP466x parts. The main difference with currently supported parts (MCP453x and alike) is the addition of a non-volatile memory in order to recall the wiper setting at power-on. This feature is currently not supported and only the volatile memory is used to set the wiper.
