habanalabs: set max power on device init per ASIC
For current devices there is a need to send the max power value to F/W during device init, for example because there might be several card types. In future devices, this info will be programmed in the device's EEPROM and will be read by F/W, and hence the driver should not send it. Modify the sending of the relevant message to be done only for ASIC types that need it.
