Subject: [PATCH 3/3 v4] blackfin: pinctrl-adi2: Enable PINCTRL framework for BF54x and BF60x.

From: Sonic Zhang <sonic.zhang@...log.com>

- Remove unused macro MAX_RESOURCES
- Override blackfin legacy peripheral pinmux request and free APIs by
devm_pinctrl_get_select_default() to init the peripheral portmux setting.

v3-chagnes:
- Move pinctrl soc data out of blackfin arch folder.
