We'll remove it.

<asm/ppc_asm.h> is already included so we don't have to have
HMT_MEDIUM or HCALL_MEDIUM defintion in that file.

As Geoff-san said, "sc 1" is not supported in Debian or our own assembler,
so we have to keep it.

We think <asm/hvcall.h> is only for IBM's hypervisor, so we don't want
to include <asm/hvcall.h> only to get HVSC definition in our hvCall.S;
so we will keep HVSC definition here.

We'll remove it.
