board-8960: Update 8960AB and 8064AB SPM sequences.

8960AB and 8064AB have a new revision of the Krait SPM hardware.
The SPM v1.15x on these targets uses a different bit to control the
apc_pdn signal.
Update the SPM sequences for standalone and power collapse to use the
new sequences.

L2 SPM or Krait WFI/Retention sequences are not affected.
