iio: mcp320x: Fix NULL pointer dereference
On reading in_voltage_scale of we got an NULL pointer dereference Oops.
The reason for this is, that mcp320x_read_raw tries to access
chip_info->resolution from struct mcp320x, but chip_info is never set.
chip_info was never set since the driver was added, but there was no
acute problem, because it was not referenced.
The acute problem exists since

iio: adc: mcp320x. Add support for more ADCs
This patch fixes the issue by setting chip_info in mcp320x_probe.
