acpi: Move maximum size logic into acpi_add_rom_blob()
We want to have safety margins for all tables based on the table type. Let's move the maximum size logic into acpi_add_rom_blob() and make it dependent on the table name, so we don't have to replicate for each and every instance that creates such tables.
