Subject: gpio: thunderx: utilize for_each_set_clump macro

Reimplement the thunderx_gpio_set_multiple function in
drivers/gpio/gpio-thunderx.c to use the new for_each_set_clump macro. 
Instead of looping for each bank in thunderx_gpio_set_multiple function,
now we can skip bank which is not set and save cycles.
