[PATCH] Documentation: hwmon: lm75: document sysfs interface

[Chen-Shi-Hong]

Document the sysfs attributes supported by the lm75 driver.

The driver exposes temp1_input, temp1_max, temp1_max_hyst, and the
standard update_interval attribute. Some chips also expose temp1_alarm.

Add a sysfs-Interface section to Documentation/hwmon/lm75.rst to
describe the supported attributes and clarify that temp1_alarm and the
write permissions of update_interval depend on the chip.

Should this section also document the temp1_label attribute?

Looking at drivers/hwmon/lm75.c, the driver exposes the temp1_label
attribute via HWMON_T_LABEL if a label device property is present.
