x86: Refactor table-writing code a little
The implementation of write_tables() is confusing because it uses the
rom_table_start variable as the address pointer as it progresses.
Rename it to rom_addr to make the code clearer. Move the rom_table_end
variable into the block where it is used.
Also update logging to use the ACPI category, now that it is available.
