habanalabs: update firmware definitions 

Add comments for the various errors and states of the firmware during boot.
Add a mapping of a new register that will tell the driver whether the
firmware executed the request from the driver or if it has encountered an
error.
Add a new enum for the possible values of this register.

*
* CPU_BOOT_ERR0_FIT_CORRUPTED FIT data integrity verification of the

*
* CPU_BOOT_ERR0_TS_INIT_FAIL Thermal Sensor initialization failed.

* mind this is a warning.
*
* CPU_BOOT_ERR0_DRAM_SKIPPED DRAM initialization has been skipped.
* Skipping DRAM initialization has been
* requested (e.g. strap, command, etc.)
* and FW skipped the DRAM initialization.
* Host can initialize the DRAM.
*
* CPU_BOOT_ERR0_BMC_WAIT_SKIPPED Waiting for BMC data will be skipped.
* Meaning the BMC data might not be
* available until reset.
*
* CPU_BOOT_ERR0_NIC_DATA_NOT_RDY NIC data from BMC is not ready.
* BMC has not provided the NIC data yet.
* Once provided this bit will be cleared.
*
* CPU_BOOT_ERR0_NIC_FW_FAIL NIC FW loading failed.
* The NIC FW loading and initialization
* failed. This means NICs are not usable.
*
* CPU_BOOT_ERR0_ENABLED Error registers enabled.
* This is a main indication that the
* running FW populates the error
* registers. Meaning the error bits are
* not garbage, but actual error statuses.
