dm: core: Switch order of pinctrl and power domain calls

Browse source 
The commit 3ad3077848 ("dm: core: device: enable power domain in probe")
introduced enabling power domain when device is probed.
By checking this sequence in Linux kernel was found that power domain is
handled first followed by pinctrl setting.

This patch is switching this order to follow Linux kernel that power
domains are handled first follow by pinctrl setting.

The issue was found on Xilinx Kria SOM where firmware is blocking setting
up pin configuration/muxes without enabling power domain for the specific
IP first.
