This updates the doc for the following places:
- Mention CRB for Bayley Bay
- Mention Congatec QEVAL 2.0 & conga-QA3/E3845
- Limit part of the QEMU paragraphs to 80 cols
- Correct some typos (drive, it's, Ubuntu)
- Add description for "console=ttyS0,115200"
- Remove CONFIG_BOOTDELAY description which is already
in x86-common.h

This adds basic BayTrail platform ASL files. They are intended to be
included in dsdt.asl of any board that is based on this platform.
Note: ACPI mode support for GPIO/LPSS/SCC/LPE are not supported for
now. They will be added in the future.

This adds several generic ASL libraries that can be included by

The comment of initializing table header revision says:
/* ACPI 1.0/2.0: 1, ACPI 3.0: 2, ACPI 4.0: 3 */
which might mislead it may increase per ACPI spec revision.
However this is not the case. It's actually a fixed number
as defined in ACPI spec, and in the laest ACPI spec 6.1,
some table header revisions are still 1. Clean these up.

- Use "U-BOOT" and "U-BOOTBL" for the OEM ID and OEM table ID.
- Do not typedef acpi_header_t, instead use struct acpi_table_hader.
- Use a shorter name aslc_id and aslc-revision.
- Change MCFG base address to use 32-bit value pairs (_l and _h).
- Apply ACPI_APIC_ prefix to MADT APIC type macros and make
their names to be more readable.
- Apply __packed to struct acpi_madt_irqoverride and struct
acpi_madt_lapic_nmi tables, as they are not naturally aligned
by the compiler which leads to wrong sizeof(struct).
- Rename model to res1 as it is reserved after ACPI spec 1.0.
- Apply ACPI_ prefix to the PM profile macros and change them
to enum.
- Add ospm_flags to FACS structure which is defined since ACPI 4.0.
