Support MAX34451, fix sensor type, enum issues

Add support for MAX34451 power sequencers, as well as fix some issues
with substring matching with regards to hwmon file prefix (sensor type)
and hwmon file suffix (sensor enumeration).
e.g vout11 , vout would be the sensor type and 11 would be the
enumeration.
Test:
Reboot BMC on a system with a MAX34451 present
which published the following sysfs hwmon labels,
e.g grep -H "" /sys/class/hwmon/hwmonXX/*_label
in10_label:vout12
in11_label:vout13
in12_label:vout16
in1_label:vout1
in2_label:vout2
in3_label:vout4
in4_label:vout5
in5_label:vout6
in6_label:vout7
in7_label:vout9
in8_label:vout10
in9_label:vout11
then did dbusctl --no-pager tree xyz.openbmc_project.PSUSensor
and saw the correct corresponding output voltage paths.
Before the patch having an enumeration > 9 would cause issues.
