intel-gpio for v5.4-1

The clean up of IRQ chip initialization has been done in few drivers.
 Stale record in MAINTAINERS database is removed.
 
 The following is an automated git shortlog grouped by driver:
 
 intel-mid:
  -  Pass irqchip when adding gpiochip
  -  MAINTAINERS: Remove stale record for gpio-intel-mid.c
 
 lynxpoint:
  -  Pass irqchip when adding gpiochip
 
 merrifield:
  -  Pass irqchip when adding gpiochip
 
 pch:
  -  Use dev_get_drvdata
