Bryan O'Donoghue 61775d54d6 i2c: qcom-cci: Fix ordering of pm_runtime_xx and i2c_add_adapter 
When we compile-in the CCI along with the imx412 driver and run on the RB5
we see that i2c_add_adapter() causes the probe of the imx412 driver to
happen.

This probe tries to perform an i2c xfer() and the xfer() in i2c-qcom-cci.c
fails on pm_runtime_get() because the i2c-qcom-cci.c::probe() function has
not completed to pm_runtime_enable(dev).

Fix this sequence by ensuring pm_runtime_xxx() calls happen prior to adding
the i2c adapter.
