gpio fixes for v5.18-rc6

- fix the bounds check for the 'gpio-reserved-ranges' device property in
  gpiolib-of
- drop the assignment of the pwm base number in gpio-mvebu (this was missed
  by the patch doing it globally for all pwm drivers)
- fix the fwnode assignment (use own fwnode, not the parent's one) for the
  GPIO irqchip in gpio-visconti
- update the irq_stat field before checking the trigger field in gpio-pca953x
- update GPIO entry in MAINTAINERS
gpio: pca953x: fix irq_stat not updated when irq is disabled (irq_mask not set)

When one port's input state get inverted (eg. from low to hight) after
pca953x_irq_setup but before setting irq_mask (by some other driver such as
"gpio-keys"), the next inversion of this port (eg. from hight to low) will not
be triggered any more (because irq_stat is not updated at the first time). Issue
should be fixed after this commit.
