Agilex5 FSBL is required to disable the power of unused peripheral SRAM blocks to reduce power consumption. Introducing a new power manager driver for Agilex5 which will be called as part of Agilex5 SPL initialization process. This driver will read the peripheral handoff data obtained from the bitstream and will power off the specified peripheral's SRAM from the handoff data values.
