patch1 is a trivial clean up: move the parameters for wait for link
into the core pcie-designware.c

Since link may be UP but still in link training, if so, we can't think
the link is up and operating correctly. So patch2 teaches
dw_pcie_link_up() beware of the PCIE_PHY_DEBUG_R1_LINK_IN_TRAINING bit.
