AMDFWtool maintains 2 copies of PSP Level2 entries - one in primary slot A (Type 0x48) and another in backup slot B (Type 0x4A). On boards which use VBOOT with 2 RW firmware slots, maintaining 2 copies of PSP Level2 entries in each FW slot is redundant and space-consuming. Introduce option to maintain only one copy of PSP Level2 entries and point to it from both slots A & B. BUG=None TEST=Build and boot to OS in Skyrim. Ensure that only one copy is added to each FW slot. This achieved a space saving of 1.5 MB in each FW slot.
