[PATCH v5 01/24] i2c: designware: Fix PM calls order in dw_i2c_plat_probe()

[Andy Shevchenko <andriy.shevchenko@linux.intel.com>]

We should not mix managed calls with non-managed. This will break
the calls order at the error path and ->remove() stages. Fix this
by wrapping PM ops to become managed one.
