[ Upstream commit 70d81f25cc92cc4e914516c9935ae752f27d78ad ]
Currently, mlxfw kernel module limits FW flash image size to be 10MB at most, preventing the ability to burn recent BlueField-3 FW that exceeds the said size limit.
Thus, drop the hard coded limit. Instead, rely on FW's max_component_size threshold that is reported in MCQI register as the size limit for FW image.
