Firmware files below 1.11 were never released to customers so no need
to support them externally.

From: Ohad Sharabi <osharabi@habana.ai>
Currently, the code contains 2 types of FW version comparison functions:
- hl_is_fw_sw_ver_[below/equal_or_greater]()
- gaudi2 specific function of the type
gaudi2_is_fw_ver_[below/above]x_y_z()
Moreover, some functions use the inner FW version which should be only
stage during development but not version dependencies.
This commit aligns all APIs to a single function that just compares the
version and return an integers indicator (similar in some way to
strcmp()).
In addition, this generic function now considers also the sub-minor FW
version.
