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.
