Hello build bot (Jenkins), Nico Huber, Tim Wawrzynczak, Angel Pons, Kyösti Mälkki, Patrick Rudolph, Karthik Ramasubramanian,

soc/intel/common/uart: Use simple(_s_) variants of PCI functions

This change updates various uart_* functions to use simple(_s_)
variants of PCI functions. This is done for a few reasons:

* __SIMPLE_DEVICE__ check can be dropped since the same data type can
  be used in early stages and ramstage.
* Removes the requirement on early stage to walk the device tree to
  get access to the device structure. This allows linker-based device
  tree optimizations for early stages.

As part of this change, uart_get_device() is refactored and a new
function uart_console_get_devfn() is added which returns pci_devfn_t
in MMCONF format. It is then used directly by the _s_ variants of PCI
functions.
