acpi.h: Small fixes and adding comments.
- Mention full name of all the tables (SSDT, FADT, etc). - Drop obsolete / incorrect "LXBIOS" reference. - Add missing ACPI address space type #defines specified in newer versions: ACPI_ADDRESS_SPACE_EC, ACPI_ADDRESS_SPACE_SMBUS. - Add missing "enum acpi_apic_types" entries: Localx2Apic, Localx2ApicNMI. - Add ACPI_FACS_64BIT_WAKE_F #define.
