Changes in V6
  - Addressed comments of Mr. Rob Herring.
    - Changed name of vendor property: sunplus,zero_func --> sunplus,zerofunc
  - Addedssed comments of Mr. Andy Shevchenko
    - Modified Kconfig (bool -> tristate) and Makefile to support 'compile as module'.
    - Re-ordered some header files.
    - Removed some useless comments.
    - Added some inline functions to simplify coding.
    - Removed checking existing of property "gpio-controller".
    - Removed redundant 'check_mul_overflow()' after a devm_kcalloc() function.
    - Added include <linux/types.h> in 'sppctl.h'
    - Modified and added some kernel-doc comments.
    - Fixed some wrong comment style of multi-line.
    - Moved struct sppctl_gpio_chip { ... }; to 'sppctl.c'.
    - Others
