net/mlxfw: Drop hard coded max FW flash image size

Browse Source 
[ 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.

Fixes: 410ed13cae ("Add the mlxfw module for Mellanox firmware flash process")
