gpio: sim: set a limit on the number of GPIOs
With the removal of ARCH_NR_GPIOS in commit 7b61212f2a07 ("gpiolib: Get
rid of ARCH_NR_GPIOS") the gpiolib core no longer sanitizes the number
of GPIOs for us. This causes the gpio-sim selftests to now fail when
setting the number of GPIOs to 99999 and expecting the probe() to fail.
Set a sane limit of 1024 on the number of simulated GPIOs and bail out
of probe if it's exceeded.
