#1710905 — [PATCH v2 2/3] PCI: mediatek: take use of bus->sysdata to get host private data

From: Honghui Zhang <honghui.zhang@mediatek.com>

Commit ae02a6dda285 ("PCI: mediatek: Add controller support for MT2712 and
MT7622") has put the mtk_pcie * into bus->sysdata, take advantage of that
to get the private data and simplify the code.
