The MMIO addresses for peripherals are being assigned by BIOS
at boot. Different BIOS versions and number of enabled peripherals
affect how those addresses are assigned. This invalidates
the addresses for UART defined in DTS. Turn on PCI enumeration
so UART addresses are probed at boot to avoid non-usable
UART and black console.

This adds a primitive board configuration for the UP Squared board
containing Apollo Lake based Pentinum and Celeron SoC. This has
been tested on model UPS-APLP4-A10-0432.
This starts from the minnowboard configuration, and document
from galileo.
