intel-gpio for v5.9-1 

* Move GPIO PMIC drivers to use IRQ chip template
 * Introduce for_each_requested_gpio() and convert existing users
 * Replace unsigned by unsigned int in few drivers
 * Fix an issue in kernel doc that validator complains about
 * Move to verbose debug level the IRQ status message in gpio-pch
 
 The following is an automated git shortlog grouped by driver:
 
 ARM/orion/gpio:
  -  Make use of for_each_requested_gpio()
 
 crystalcove:
  -  Use irqchip template
  -  changed every 'unsigned' to 'unsigned int'
 
 gpiolib:
  -  Introduce for_each_requested_gpio_in_range() macro
 
 gpio-ml-ioh:
  -  Fix missing ':' in 'struct ioh_gpio_reg_data
