83ea24fd45 gpio: xlp: Convert to use gpiolib irqchip helpers
commit "325f0a (MIPS: Netlogic: Use chip_data for irq_chip methods)"
Updates "mips/netlogic/common/irq.c" to use chip_data to store interrupt
controller data pointer. Before this commit handler_data was used to
store interrupt controller data which caused errors while using
gpiochip_set_chained_irqchip.

Update XLP GPIO driver to use the gpiolib irqchip helpers.
And add missing depends on OF_GPIO in Kconfig.

a0c81ce087 gpio: xlp: fix error return code
Return a negative error code on failure.

A simplified version of the semantic match that finds this problem is as
follows: (http://coccinelle.lip6.fr/)

// <smpl>
@@
identifier ret; expression e1,e2;
@@
(
if (\(ret < 0\|ret != 0\))
 { ... return ret; }
|
ret = 0
)
... when != ret = e1
    when != &ret
*if(...)
{
  ... when != ret = e2
      when forall
 return ret;
}
// </smpl>

ff71880006 gpio: xlp: GPIO controller for Netlogic XLP SoCs
Add GPIO controller driver for Netlogic XLP MIPS64 SOCs.

This driver is instantiated by device tree and supports interrupts
for GPIOs.
