linux-libc-headers: refresh patch to add Digi debounce IOCTL to kernel v5.4

Digi customized linux kernel gpio.h file to allow debounce functionality by the
user space through the character device.
This commit patches the gpio.h file that is used to generate the SDK (which comes
from kernel 5.4) with Digi debounce additions.
