[U-Boot] [PATCH v2 1/7] arm: K3: Avoid use of MCU_PSRAM0 before SYSFW is loaded

On HS devices the 512b region of reset isolated memory called MCU_PSRAM0 is firewalled by default. Until SYSFW is loaded we cannot use this memory. It is only used to store a single value left at the end of SRAM by ROM that will be needed later. Save that value to a global variable stored in the
