Subject: [PATCH] habanalabs: remove deprecated firmware states

From: Ofir Bitton <obitton@...ana.ai>

During driver and F/W handshake, driver waits for F/W to reach
certain states in order to progress with the boot flow.
Some of the states were deprecated a long time ago and were never
present on official firmwares. Therefore, let's remove them from
the handshake process.
