In the past, we'll set the HCR_EL2 while Xen is booting in init_traps.
And the command line parameter "vwfi" will affect the value of setting
HCR_EL2. So we placed the parse_vwfi in trap.c to avoid exporting vwfi
to other source files.

But in previous patch of this series, we had removed the HCR_EL2 setting
from init_traps. Keep parse_vwfi in trap.c is pointless. And we will set
the HCR_EL2 for each domain individually while it's creating in the later
patch of this series. So we move parse_vwfi to domain.c for preparation.
