usb: typec: tcpm: fix EPR AVS APDO maximum voltage decoding
pdo_epr_avs_apdo_max_voltage_mv() extracts the EPR AVS minimum-voltage
field instead of the maximum-voltage field. As a result, an EPR AVS APDO
with different minimum and maximum voltages is decoded as having
identical limits. The currently visible effect is that
tcpm_log_source_caps() reports a min-min voltage range.
Extract PDO_EPR_AVS_APDO_MAX_VOLT in the maximum-voltage accessor.
