habanalabs: power management through sysfs is only for GOYA
The ability of setting power management properties by the system administrator (through sysfs properties) is only relevant for the GOYA ASIC. Therefore, move the relevant sysfs properties to the GOYA sysfs specific file, to make the properties appear in sysfs only for GOYA cards.
