The device dependent options which are going to be different for devices
which will be supported  in the future by this driver,
were moved in chip info for a more generic driver. This patch allows
supporting more devices by the driver. Also, it is an intermediate
step of adding support for ad7616 in software mode.

As per below information

GFP_KERNEL  FLAG

This is a normal allocation and might block. This is the flag to use in
process context code when it is safe to sleep.

GFP_ATOMIC FLAG

The allocation is high-priority and does not sleep. This is the flag to
use in interrupt handlers, bottom halves and other situations where you
cannot sleep

And we can take advantage of GFP_KERNEL , as when system is in low
memory chances of getting success is high compared to GFP_ATOMIC.

As visornic_probe is in  process context we can use GPF_KERNEL.

Many of the functions in kpc_i2c log debug-level messages to the
kernel log message buffer upon invocation. This is unnecessary, as
debugging tools like kgdb, kdb, etc. or the tracing tool ftrace
should be able to provide this same information. Therefore, remove
these print statements.
