soc/amd/common/block/gpio_banks: use unsigned int for gevent parameter
A valid GEVENT number is never negative. The local variable in
set_single_gpio still needs to be a signed integer, since the return
value of get_gpio_gevent being -1 indicates that the GPIO can't generate
a GEVENT. The check for that makes the function return before calling
program_smi of program_sci, so the parameter of those functions can be
changed to unsigned.
