BIOS restructure exported memory resources for Punit
in acpi table, So update resources for Punit.
Signed-off-by: Qipeng Zha <qipeng....@intel.com>
---
change in v10
update comments and macros related to styles;
use %pR to dump resource structure.
change in v9
rename indexes of all acpi resources;
add comments for punit_res;
