[PATCH 1/3] pci: Update the highest subordinate bus number for bridge setup

[Tim Harvey <tharvey@gateworks.com>]

From: Masami Hiramatsu <masami.hiramatsu@linaro.org>

Update the highest subordinate bus number after probing the devices
under the bus for setting up the bridge correctly.
The commit 42f3663a3f67 ("pci: Update to use new sequence numbers")
removed this but it is required if a PCIe bridge is under the bus.

Fixes: 42f3663a3f67 ("pci: Update to use new sequence numbers")
