[PATCH i-g-t v2 4/6] tools/intel-gfx-fw-info: Override kernel types

[Lucas De Marchi <lucas.demarchi@intel.com>]

Previously we were defining u32 type as part of the string we are
loading. However in order to use other types like u8 and u16 in upcoming
changes, it would be better to have them all defined in a single place.
We can't create a typedef like done with u32 because cstruct already
defines a few types for convenience. However it's very surprising it's
defining e.g. u8 as a 64-bit variable.
