acpi_pld: Make it easier to define the ACPI USB device groups

The Linux kernel can use the ACPI _PLD group information to
determine peer ports.  Currently to define the group information
the devicetree must provide a complete _PLD structure.  This
change pulls the group information into a separate structure that
can be defined in devicetree.  This makes it easier to set for
USB devices in devicetree that do not need a full custom PLD.

This was tested on a sarien board with the USB devices defined
by verifying that the USB 2/3 ports are correctly identified
with their peer in sysfs.
