mt76: add LINUXKPI_PARAM_PREFIX for module_param*

In order to not overwrite sysctl/tunables under compat.linuxkpi
we need to prefix the module_param* names with a per-driver/file
designator to make them (more) uniq.  Add the FreeBSD specific
LINUXKPI_PARAM_PREFIX defines for that where missing in mt76.
