Subject: [PATCH v3 1/6] pinctrl: s32g2: use of_device_get_match_data() to get device data

Choose of_device_get_match_data() instead of indirect reference via
of_match_device() so that the implementation can be more concise.

Changes in v3:
- Declare the struct var 'info' as const and remove unnecessary type casting.
