[coreboot-gerrit] Change in coreboot[master]: arch/x86/tables: Move max ACPI table size to Kconfig

[Duncan Laurie (Code Review)]

Hello build bot (Jenkins), Furquan Shaikh, Angel Pons,

I'd like you to reexamine a change. Please visit

arch/x86/tables: Move max ACPI table size to Kconfig

The maximum ACPI table size is currently hardcoded to 144 KiB.
When using QEMU with TPM enabled there is ~200 KiB of ACPI tables
returned by the fw_cfg interface, so in order to allow this to be
overridden by a mainboard move it to Kconfig.

This is seen when using a TPM with qemu as it will hang when
processing the fw_cfg tables.

qemu-system-x86_64 \
  -machine q35 -enable-kvm -vga virtio -serial stdio \
  -drive 'id=hd,file=disk.bin' -bios coreboot.rom \
  -chardev 'socket,id=swtpm,path=/tmp/swtpm/swtpm-sock' \
  -tpmdev 'emulator,id=tpm0,chardev=swtpm' \
  -device 'tpm-tis,tpmdev=tpm0'
