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

The MCP3425 is a single channel up to 16-bit A/D converter which has
features:
- On-Board Programmable Gain Amplifier (PGA):
- Gains of 1, 2, 4 or 8
- Programmable Data Rate Options:
- 15 SPS (16 bits), 60 SPS (14 bits), 240 SPS (12 bits)
The mcp3422 driver also supports the MCP3421 which is a single channel.
So we can support MCP3425 with a little changes to mcp3422 driver.

The mcp3421 is the single channel variant of the mcp342x family. Support
is straight forward, only the channels array has to be added for this
chip.

i2c_driver does not need to set an owner because i2c_register_driver()
will set it.

This patch fixes uncorrect order of mcp3422_scales table, the values
was erroneously transposed.
It removes also an unused array and a wrong comment.

the index argument to sign_extend32() gives the bit position (from 0)
to the sign bit
so e.g. if the measurement has 16-bit resolution, we need to pass 15;
a measurement of 0x8000 should be reported as -32768, not 32768
