[PATCH 3/3] pcie_root_port: reorder procedures in realize()

[Tom Yan]

There are a bunch of pcie_cap_*_init() in the realize method of the
pcie root port devices that do not have return value. They can probably
be called after the slot is successfully added to an created chassis
(i.e. the slot number to use is final).
of them makes use of the slot number.
