hwmon: (pmbus/adm1266) include adapter number in GPIO line label
Platforms that fit more than one ADM1266 on different I2C buses at
the same 7-bit slave address (a common shelf-management pattern,
e.g. one device per power domain) end up with duplicate GPIO line
labels because the existing format only includes the slave address.
Including the adapter number disambiguates them.
The adapter number is formatted as decimal to match the i2c-N
convention used elsewhere in Linux (sysfs paths, dev nodes); the
slave address keeps its conventional hexadecimal form.
The label is purely informational (visible via gpioinfo and the
gpiochip /sys/class/gpio name); no DT or ABI consumer parses it.
