Add validation for FW version in order to prevent driver initialization
in case FW version is older than expected. FW version validation is
necessary, because use of a new field 'num_of_modules' in MGPIR register
is not backward compatible. FW 'minor' and 'subminor' versions are
expected to be greater than or equal to 2000 and 1886, respectively.
