Switching to the _scoped() version removes the need for manual
calling of fwnode_handle_put() in the paths where the code
exits the loop early. In this case that's all in error paths.

In mcp3564_config() fix the hardware identification logic
based on the hardware ID registers. Second part of the code was
disabled by an logic error.
Fix a typo related to the "MODULE_DESCRIPTION".

The current implementation uses the AND (&&) operator to check if the
value to write for IIO_CHAN_INFO_CALIBBIAS and IIO_CHAN_INFO_CALIBSCALE
is within the valid ranges.
The evaluated values are the lower and upper limits of the ranges,
so this operation always evaluates to false.
The OR (||) operator must be used instead.
