serial: 8250_lpss: enable MSI for sure
The commit 4fe0d154880b ("PCI: Use positive flags in pci_alloc_irq_vectors()")
replaces flags from negative to positive values which makes mandatory to have
the last argument in pci_alloc_irq_vectors() non-zero (if we want to be no-op).
This basically drops MSI enabling in 8250_lpss driver.
Restore desired behaviour in 8250_lpss by passing PCI_IRQ_ALL_TYPES instead of
0 to pci_alloc_irq_vectors().
Fixes: 60a9244a5d14 ("serial: 8250_lpss: enable MSI for Intel Quark")
