Introduce a Kconfig variable that the SoC can set to indicate the
number of instances in Device Tree. This also fixes the accuracy of
the Elkhart Lake instance count where the code was previously assuming
up to 12 instances even though DT lists 15 nodes.

The new APIs are not only dealing with cache flushing. Rename the
Kconfig symbol to CACHE_MANAGEMENT to better reflect this change.

Add support for fixed MMIO (non-PCIe) UART devices for the early
serial. All we need to do is to detect if the device is on PCIe and
set the right register address define based on that.

Add definitions for UART1/2 when they're accessible through fixed MMIO
addresses (instead of PCIe), and mark all UARTs not normally available
with the UEFI BIOS as "disabled".
