Subject: [PATCH 0/5] gpio: thunderx: Marvell GPIO changes.

This patch includes the following changes:

- Using irqsave/irqrestore spinlock variants to avoid any potential
  deadlock in case of GPIO as IRQ
- Introducing a new device tree option 'pin-cfg' which can be used to setup
  mode of one or several GPIO pins. It can be used to choose pin's
  function, filtes, polarity and direction.
- Extending PIN_SEL_MASK to cover for otx2 platform
- In case of level irq, the current handle is not unmasking the GPIO
  interrupt, so using handle_level_irq, which will allow next interrupt
  to be handled.

All the changes have been internally verified on Marvell otx2 platforms.
