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.

Previously most drivers that used a i2c_check_functionality() check
condition required various error codes on failure. This patchset
converts to a standard of -EOPNOTSUPP
