The Fintek F81504/508/512 is a multi-function PCIE devices.
IC function list:
F81504: Max 2x8 GPIOs and max 4 serial ports
port2/3 are multi-function
F81508: Max 6x8 GPIOs and max 8 serial ports
port2/3 are multi-function, port8/9/10/11 are gpio only
F81512: Max 6x8 GPIOs and max 12 serial ports
port2/3/8/9/10/11 are multi-function
It had implemented in 8250_pci.c with basic serial port function.
We want to complete it. Alan & Andy recommend us to rewrite and
spilt our driver with MFD architecture.

Paul recommed us do less code deletion to avoid confusing problem when
bisect.
https://lkml.org/lkml/2016/1/18/646
So we'll do this with following patches.
1. Add MFD core driver.
2. Add GPIOLIB driver.
3. Add serial port driver.
4. Remove old driver in 8250_pci.c
It can be workable when applied patches 1~3. After apply patch 4,
the device will control by F81504 MFD core driver.
