549fdb9ec9 i2c: mchp_xec: define driver instaces based on device tree...
...instead of kconfig.

This provides a bit more flexibility in defining driver
instances. Also, since the DTS defines 5 I2C controllers,
the driver code is extended to cover all 5 if the controllers
are enabled.

4c32258606 style: add braces around if/while statements
Per guidelines, all statements should have braces around them. We do not
have a CI check for this, so a few went in unnoticed.
