In very very space-constrained devices even the full UART driver is too
large. In this case the debug UART can still be used in some cases.
Add options to enable the UART driver in SPL and U-Boot proper. Enable both
options by default.

Use the driver model version of the function to find the BAR. This updates
the fdtdec function, of which ns16550 is the only user.
The fdtdec_get_pci_bdf() function is dropped for several reasons:
- with driver model we should use 'struct udevice *' rather than passing the
device tree offset explicitly
- there are no other users in the tree
- the function parses for information which is already available in the PCI
device structure (specifically struct pci_child_platdata which is available
at dev_get_parent_platdata(dev)

This commit does not have an issue in itself, but it revelead a problem
with the Ethernet initialization.
As per the AR8035 datasheet:
"For a reliable power on reset, suggest to keep asserting the reset
low long enough (10ms) to ensure the clock is stable and clock-to-reset
1ms requirement is satisfied."
So do as suggested and keep the reset low for 10ms.
Also add a 100us delay after deasserting the reset line
to guarantee that the PHY ID can be read correctly and the Atheros
PHY can be loaded as per Troy Kisky's suggestion.
