setup vwfi correctly on cpu0

parse_vwfi runs after init_traps on cpu0, potentially resulting in the
wrong HCR_EL2 for it. Secondary cpus boot after parse_vwfi, so in their
case init_traps will write the correct set of flags to HCR_EL2.

For cpu0, fix the issue by changing HCR_EL2 setting from a new
presmp_initcall.
