Mauri Sandberg 6a6f9e73dd packages: kernel: add gpio-nxp-74hc153
NXP 74HC153 is a GPIO expander. Its original source cide sits in ar71xx
architecture tree. It has been slightly modified to get GPIO pin
configuration from the device tree rather than a MACH file.

 Changes to the source file:
  - Remove struct nxp_74hc153_config
  - in nxp_74hc153_probe(), fetch GPIO configuration from device tree
  - allow GPIO framework decide the base number by passing -1 to it
  - remove support for kernel versions below 4.5.0
  - add OF device compatibility string

 Create a package for inclusion in image.
