pinctrl: armada-37xx: Correct mpp definitions

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]
