x86/boot: Early parse RSDP and save it in boot_params
The RSDP is needed by KASLR so parse it early and save it in
boot_params.acpi_rsdp_addr, before KASLR setup runs.
RSDP is needed by other kernel facilities so have the parsing code
built-in instead of a long "depends on" line in Kconfig.
[ bp:
- Trim commit message and comments
- Add CONFIG_ACPI dependency in the Makefile
- Move ->acpi_rsdp_addr assignment with the rest of boot_params massaging in extract_kernel().
