acpi: Use ACPI macros to configure USB port _PLD object
This patch adds two ACPI macros for USB port A and C _PLD object
configuration as:
1. ACPI_PLD_TYPE_A
2. ACPI_PLD_TYPE_C
The configurable parameters are
- Panel, Port is exposed on which face of a panel.
- Horizontal, Horizontal position on the panel where the device
connection point resides.
- Group
- Token, Unique numerical value identifying a group.
- Position, Identifies this device connection point’s position
in the group (i.e. 1st, 2nd).
