MCP466x
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.

Actually I2C_FUNC_SMBUS_WORD_DATA isn't need for this device, and regmap
handles all single byte reads transparently.

Use const pointer to element from model configuration array rather then array
index, as it will not change anyway.

Change i2c_check_functionality condition check return from ENOTSUPP to
EOPNOTSUPP which is now the standard return code.

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
