x86: Move acpi_get_rsdp_addr() ACPI tables to the writer
Move this over to use a writer file, moving the code from the x86
implementation.
There is no need to store a separate variable since we can simply access
the ACPI context.
With this, the original monolithic x86 function for writing ACPI tables
is gone.
Note that QEMU has its own implementation.
