Subject: [PATCH v3 20/30] ABI: sysfs-class-pwm: use wildcards on What definitions

An "N" upper letter is not a wildcard, nor can easily be identified
by script, specially since the USB sysfs define things like.
bNumInterfaces. Use, instead, <N>, in order to let script/get_abi.pl
to convert it into a Regex.
