[PATCH 01/10] mfd: Juniper PTXPMB CPLD Multi-function core driver

From: Guenter Roeck <groeck at juniper.net>
Add Juniper's PTXPMB FPGA CPLD driver. Those FPGAs
are present in Juniper's PTX series of routers.
There are two variants, the original which is found on the
PTXPMB_P2020, PTXPMB_P2020_SPMB based on a Freescale P2020 SoC,
and PTXPMB_P5040 based on a Freescale P5040 SoC.
The new variant NGPMB is present on a new line of x86 based
boards (currently only the Gladiator FPC).
Both variants provide a hardware watchdog, i2c mux and a
gpio block, with the i2c mux block being different.
