x86: coreboot: Collect the address of the ACPI tables
At present any ACPI tables created by prior-stage firmware are ignored.
It is useful to be able to view these in U-Boot.
Pick this up from the sysinfo tables and display it with the cbsysinfo
command. This allows the 'acpi list' command to work when booting from
coreboot.
Adjust the global_data condition so that acpi_start is available even if
table-generation is disabled.
