power: supply: Add PD SPR AVS support to USB type enum

Add two new members to the power_supply_usb_type to represent the
USB Power Delivery (PD) Standard Power Range (SPR) Adjustable Voltage
Supply (AVS) charging types:

POWER_SUPPLY_USB_TYPE_PD_SPR_AVS: For devices supporting only the
PD SPR AVS type.

POWER_SUPPLY_USB_TYPE_PD_PPS_SPR_AVS: For devices that support both
PD Programmable Power Supply (PPS) and PD SPR AVS.
