Subject: [PATCH] typec: tcpm: fix a typo in the comparison of pdo_max_voltage

From: Colin Ian King <colin.king@...onical.com>

There appears to be a typo in the comparison of pdo_max_voltage[i]
with the previous value, currently it is checking against the
array pdo_min_voltage rather than pdo_max_voltage. I believe this
is a typo. Fix this.
