[PATCH v7 07/14] gpio: thunderx: Use the default parent apis for {request,release}_resources

[Lokesh Vutla]

thunderx_gpio_irq_{request,release}_resources apis are trying to
{request,release} resources on parent interrupt. There are default
apis doing the same. Use the default parent apis instead of writing
the same code snippet.
