Subject: [PATCH net-next v13 13/15] net: stmmac: dwmac-loongson: Drop pci_enable/disable_msi temporarily

The LS2K2000 patch added later will alloc vectors, so let's
remove pci_enable/disable_msi temporarily to prepare for later
calls to pci_alloc_irq_vectors/pci_free_irq_vectors. This does
not affect the work of gmac devices, as they actually use intx.
