misc: sgi-gru: Don't cast parameter in bit operations

While in this particular case (*) it would not be an issue,
the pattern itself is bad and error prone in case somebody
blindly copies to their code.

Don't cast parameter to unsigned long pointer in the bit
operations. Note, new compilers might warn on this line for
potential outbound access.

*) it seems a dead code, so remove it all for good
