[PATCH 4.2 082/120] serial: 8250_pci: Add support for Pericom PI7C9X795[1248]

[Greg Kroah-Hartman]

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

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

From: Adam Lee <adam.lee@xxxxxxxxxxxxx>

commit 89c043a6cb2d4525d48a38ed78d5f0f5672338b3 upstream.

Pericom PI7C9X795[1248] are Uno/Dual/Quad/Octal UART devices, this
patch enables them, also defines PCI_VENDOR_ID_PERICOM here.
