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.
