drm/bridge: tpd12s015: Fix irq registering in tpd12s015_probe
gpiod_to_irq() return negative value in case of error,
the existing code doesn't handle negative error codes.
If the HPD gpio supports IRQs (gpiod_to_irq returns a
valid number), we use the IRQ. If it doesn't (gpiod_to_irq
returns an error), it gets polled via detect().
