If there are no parent resources do not call irq_chip_request_resources_parent at all as this will return an error.
This resolves a regression where devices using a thunderx gpio as an interrupt would fail probing.

This patch does not apply to the mainline kernel or v5.6-rc1.
Please verify:
- If the problem is still in v5.6 (we refactored the driver to use GPIOLIB_IRQCHIP)
Linus,
Sorry, another issue was keeping me from being able to boot 5.6-rc but that's now understood and I can confirm the issue is not present in v5.6-rc5
- If not, only propose it for linux-stable v5.5 etc.
Yes, needs to be applied to v5.2, v5.3, v5.4, v5.5. I cc'd stable. If I need to re-submit please let me know.
