[PATCH 4.14 051/106] pinctrl: armada-37xx: Correct mpp definitions

From: Marek Behún <marek.behun@nic.cz>

commit 823868fceae3bac07cf5eccb128d6916e7a5ae9d upstream.

This is a cleanup and fix of the patch by Ken Ma <make@marvell.com>.

Fix the mpp definitions according to newest revision of the
specification:
- northbridge:
fix pmic1 gpio number to 7
fix pmic0 gpio number to 6
- southbridge
split pcie1 group bit mask to BIT(5) and BIT(9)
fix ptp group bit mask to BIT(11) | BIT(12) | BIT(13)
add smi group with bit mask BIT(4)

[gregory: split the pcie group in 2, as at hardware level they can be
configured separately]
