Liav A 6131048a5f Kernel: Map PCI devices only once during boot ...

Instead of mapping a 4KB region to access device configuration space
each time we call one of the PCI helpers, just map them once during
the boot process.
Then, if we request to access one of those devices, we can ask the
PCI subsystem to give us the virtual address where the device's
configuration space is mapped.
