i2c: qcom-geni: Fix runtime PM mismatch with child devices
We need to enable runtime PM on this i2c controller before populating
child devices with i2c_add_adapter(). Otherwise, if a child device uses
runtime PM and stays runtime PM enabled we'll get the following warning
at boot.
Enabling runtime PM for inactive device (a98000.i2c) with active children
[...]
Call trace:
pm_runtime_enable+0xd8/0xf8
geni_i2c_probe+0x440/0x460
platform_drv_probe+0x74/0xc8
[...]
Let's move the runtime PM enabling and setup to before we add the
adapter, so that this device can respond to runtime PM requests from
children.
