p9_pre_poweron, p9_set_fsi_gp_shadow: Merge flush values, fix ROOT_CT…

…RL2(5)

Have pre_poweron use constants from p9_set_fsi_gp_shadow so we only have
one additional copy of the flush values outside of the VHDL itself.

Also fix ROOT_CTRL2(5) so that PIB traces actually capture request and
response data after IPL.
