Subject: [PATCH v1 - resent 4/5] i2c: busses: Allow configurable adapter id for mlxcpld

From: Michael Shych <michaelsh@...lanox.com>

It allows mlxcpld driver to be connected to pre-defined adapter number
equal or greater than one, in order to avoid current limitation, assuming
usage of id number one only.
