gpio updates for v5.5

- only get the second IRQ when there is more than one IRQ in mxc
- move the code around in lineevent_create() for some shrinkage
- fix formatting for GPIO docs
- add DT binding for r8a774b1
- convert drivers that prevously used nocache ioremap() to using regular
  devm_platform_ioremap_resource()
- remove some redundant error messages
- shrink object code in 104-idi-48e
- drop an unneeded warning from gpiolib-of
