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.
