habanalabs: power management through sysfs is only for GOYA

Browse Source 
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.
