net: pch_gbe: Add cache maintenance

On MIPS systems DMA isn't coherent with the CPU caches unless an IOCU is
present. When there is no IOCU we need to writeback or invalidate the
data caches at appropriate points. Perform this cache maintenance in
the pch_gbe driver which is used on the MIPS Boston development board.

net: pch_gbe: CPU accessible addresses are virtual

Use the virt_to_bus & bus_to_virt functions rather than phys_to_bus &
bus_to_phys, since the addresses accessed by the CPU will be virtual
rather than physical. On MIPS physical & virtual addresses differ as we
use virtual addresses in kseg0, and attempting to use physical addresses
directly caused problems as they're in the user segment which would be
mapped via the uninitialised TLB.

net: pch_gbe: Make 64 bit safe

The pch_gbe driver previously casted pointers to & from unsigned 32 bit
integers in many locations. This breaks the driver on 64 bit systems,
producing streams of compiler warnings about mismatched pointer &
integer sizes and then failing to keep track of addresses correctly at
runtime.

Fix the driver for 64 bit systems by using unsigned longs in place of
the previously used 32 bit integers.

net: pch_gbe: Use dm_pci_map_bar to discover MMIO base

Reading the PCI BAR & converting the result to a physical address is not
safe across all architectures. For example on MIPS the virtual:physical
mapping is not 1:1, so we cannot directly make use of the physical
address.

Use the more generic BAR-mapping function dm_pci_map_bar to discover the
MMIO base address, which should work across architectures.
