[6.6,0/3] Fix PPS channel routing

Message

On certain i.MX8 series parts [1], the PPS channel 0
is routed internally to eDMA, and the external PPS
pin is available on channel 1. In addition, on
certain boards, the PPS may be wired on the PCB to
an EVENTOUTn pin other than 0. On these systems
it is necessary that the PPS channel be able
to be configured from the Device Tree.
