Bin Meng 95e50dd197 x86: Do not clear high table area for S3 
When SeaBIOS is being used, U-Boot reserves a memory area to be
used for configuration tables like ACPI. But it should not be
cleared otherwise ACPI table will be missing.

Bin Meng 789b6dcecc x86: Prepare configuration tables in dedicated high memory region 
Currently when CONFIG_SEABIOS is on, U-Boot allocates configuration
tables via normal malloc(). To simplify, use a dedicated memory
region which is reserved on the stack before relocation for this
purpose. Add functions for reserve and malloc.
