net: pcnet: use pci_virt_to_mem to obtain buffer addresses
The pcnet driver uses the pci_phys_to_mem function to get the memory address of the DMA buffers. This This assumes an 1:1 mapping between the PCI and physical memory which is not true on all platforms. On MIPS platform U-Boot is running within a mapped memory region, and the pci_phys_to_mem macro can't be used to obtain the memory address of the buffers.
