[PATCH v4 0/5] Add gpio support to Broadcom Cygnus SoC

[Ray Jui]

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 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
