728c4afc39 x86: acpi: Reorder code in acpi_table.h
Reorder the ACPI tables appearance by following the order:
RSDP, RSDT, XSDT, FADT, FACS, MADT, MCFG. And adjust the
table flag defines accordingly.

8a8c035255 x86: acpi: Various changes to acpi_table.h
- 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.

f4446629c9 x86: acpi: Remove unused codes
- Remove #include <> header files.
- Remove APM_CNT register defines, which should not be here as
  they are SMI related.
- Remove MP_IRQ_ defines as they are duplicates of the same ones
  in asm/mpspec.h.
- Remove ACTL register defines, which should not be here as they
  are chipset specific.
- Remove functional fixed hardware defines, which are not used.
- Remove dev_scope related defines, which are not used.

3a2a3d0b48 acpi: Explicitly spell out dsdt.c in the make rule
Currently the make rule for dsdt.c uses a wildcard, as below:

  $(obj)/%.c:    $(src)/%.asl

To avoid any side effect, explicitly mention dsdt.c as this is
the file we intend to use for ACPI DSDT AML generation.
