device/pci_early: Fixes for __SIMPLE_DEVICE__

The feature is used to enable PCI MMIO accesses behind
PCIe links (or bridges) before PCI enumeration has been
completed.

Add the feature for bootblock, verstage and postcar, it
is required with add-on PCIe serial cards for early
console output. It's up to the board specific code to
configure PCIe root port prior to calling console_init()
for this to work.

Remove feature from ramstage, it bypasses any resource
allocations and bus number assignments.

For the moment PCI configuration support before ramstage
is available only on ARCH_X86.

Also switch from device_t to pci_devfn_t.
