mfd: intel-lpss: Return error code received from the IRQ API

Browse source

platform_get_irq() returns a negative error code to indicate an error.
As does pci_alloc_irq_vectors() and pci_irq_vector(). So in
intel_lpss_probe() the erroneous IRQ would be better returned as is.

The pci_alloc_irq_vectors() call and platform_get_irq() guarantee
that IRQs will not be 0, so we'll drop that check as well.
