Subject: [ 46/59] pch_uart: Set PCIe bus number using probe parameter

3.0-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Tomoya MORINAGA <tomoya-linux@....okisemi.com>

commit 6c4b47d243112e98811ce0da7bbb32cc3857dd1a upstream.

Currently, PCIe bus number is set as fixed value "2".
However, PCIe bus number is not always "2".
This patch sets bus number using probe() parameter.
