Subject: [PATCH v6 0/3] Add gpio support to Broadcom Cygnus SoC

This patchset contains the initial GPIO support for the Broadcom Cygnus SoC.
Cygnus has 3 GPIO controllers: 1) the ASIU GPIO; 2) the chipCommonG GPIO;
and 3) the ALWAYS-ON GPIO. All 3 types of GPIO controllers are supported by
the same Cygnus GPIO driver

Changes from v5:
 - Get rid of DT property "linux,gpio-base". Use dynamic allocation for GPIO base
   number

Changes from v4:
 - Use DT property "linux,gpio-base" to define GPIO base number
 - factorize common code to improve code readability and reduce code size
 - remove "bcm_" prefix on function and struct names
 - improve debugging prints
 - default GPIO_BCM_CYGNUS to y in Kconfig (it still depends on
   ARCH_BCM_CYGNUS). This way we do not need to select it from the
   arch/arm/mach-bcm/Kconfig
 - Get rid of redundant MAINTAINER entry for this driver. It will be maintained
   by Broadcom iProc/Cygnus maintainers
 - Update device tree document based on driver changes

Changes from v3:
 - Fix dt property tpyo
 - Fix incorrect GPIO compatible ID in device tree binding document example

Changes from v2:
 - Consolidate different compatible IDs into "brcm,cygnus-gpio"
 - Get rid of redundant "no-interrupt" property

Changes from v1:
 - Get rid of inline qualifier
 - Get rid of redundant check in the ISR
 - Other minor fixes to imrove code readability
