[RESEND PATCH v3 2/3] PCI: switchtec: Replace pci_alloc_irq_vectors() with pcim_alloc_irq_vectors()

[Shawn Lin <shawn.lin@rock-chips.com>]

Replace pci_alloc_irq_vectors() with pcim_alloc_irq_vectors() to
explicitly request devres-managed interrupt vectors. This makes the
driver's intention clear and avoids the ambiguous implicit management
previously provided by pcim_enable_device().

The change prepares the driver for the eventual removal of the hybrid
IRQ management pattern from pcim_enable_device(), ensuring consistent
resource management through devres.
