On qemu-x86_64_defconfig the following was observed:
=> efidebug tables 00000000000f0074 eb9d2d31-2d88-11d3-9a16-0090273fc14d SMBIOS table
The SMBIOS configuration table does not point to a paragraph-aligned (16 byte aligned) address. The reason is that in write_tables() rom_addr is not aligned and copied to gd->arch.smbios_start.
The Simple Firmware Interface requires that the SFI table is paragraph- aligned but our code does not guarantee this.
As all tables written in write_tables() must be paragraph-aligned, we should implement the address rounding in write_tables() and not in table specific routines like copy_pirq_routing_table().
Add paragraph-alignment in write_tables().
