usb: typec: pd: Register SPR AVS caps with usb_power_delivery class
usb_power_delivery class will now display AVS cap as
`spr_adjustable_voltage_supply`. `maximum_current_9V_to_15V` and
`maximum_current_15V_to_20V` shows the corresponding current limits
in mA. `peak_current` follows the same convention as fixed_supply
where the value reported in the capabilities message is displayed
as is.
Sample output with an SPR AVS capable PD charger:
$cat /sys/class/usb_power_delivery/pd1/source-capabilities/5:spr_adjustable_voltage_supply/maximum_current_9V_to_15V
4000mA
$cat /sys/class/usb_power_delivery/pd1/source-capabilities/5:spr_adjustable_voltage_supply/maximum_current_15V_to_20V
3350mA
$cat /sys/class/usb_power_delivery/pd1/source-capabilities/5:spr_adjustable_voltage_supply/peak_current
