gpiolib: add gpiod_multi_set_value_cansleep() 



Add a new gpiod_multi_set_value_cansleep() helper function with fewer
parameters than gpiod_set_array_value_cansleep().

Calling gpiod_set_array_value_cansleep() can get quite verbose. In many
cases, the first arguments all come from the same struct gpio_descs, so
having a separate function where we can just pass that cuts down on the
boilerplate.
