mb/emulation/qemu-q35: Increase max size of ACPI tables
When the TPM is enabled in QEMU the fw_cfg interface will return
~200KiB of ACPI tables, so this needs to be increased from the default
in order to be able to boot.
This is seen when using a TPM with qemu as it will hang when
processing the fw_cfg tables.
