For clarity, we now prefer y|n over 0|1 as the values of boolean options on
make command lines. This patch applies this preference to the Makefile of
the device model and tools, while RELEASE=0|1 is still supported for
backward compatibility.

PCI spec said that BAR base should be naturally aligned. But on
ACRN if the bar size < PAGE_SIZE, BAR base should be aligned with
PAGE_SIZE. This is because the minimal size that EPT can map/unmap
is PAGE_SIZE.

GPA base of SW SRAM can't be hardcoded as physical address
of SW SRAM(HPA), as this HPA may vary on different platform.
This patch reserves a dedicated memory slot[GPA: 2G - 8M, 2G)
as SW SRAM region.

This patch prepares vRTCT for post-RTVM instead of
pass-thru native RTCT:
- Configurations are based on Service VM native RTCT.
- Remap vLAPIC IDs in vRTCT.
- Remap base address of SW SRAM memory regions
from HPA to GPA.
- HPA base of Software SRAM shall be parsed from PTCT
instead of hardcoding.
