Subject: [PATCH 1/2] habanalabs: modify wait for boot fit in dynamic FW load

From: Ohad Sharabi <osharabi@...ana.ai>

In the dynamic FW load protocol the boot status is updated to
"Ready to Boot" once uboot is active.

Polling on other boot status values is a residue of code duplication
from the static protocol and should be removed.
