[PATCH net-next 1/2] net: atlantic: align return value of ver_match function with function name

[Mark Starovoytov]

This patch aligns the return value of hw_atl_utils_ver_match function with
its name.
Change the return type to bool, because it's better aligned with the actual
usage. Return true when the version matches, false otherwise.
