Use the System Firmware (SYSFW) loader framework to load and start the SYSFW as part of the AM642 early initialization sequence. Also make use of existing logic to detect if ROM has already loaded sysfw and avoided attempting to reload and instead just prepare to use already running firmware.

While at it also initialize the MAIN_UART1 pinmux as it is used by SYSFW to print diagnostic messages.

From: Suman Anna s-anna@ti.com

The AM642 SoCs use the Main R5FSS0 as a boot processor, and runs the R5 SPL that performs the initialization of the System Controller processor and starting the Arm Trusted Firmware (ATF) on the Arm Cortex A53 cluster. The Core0 serves as this boot processor and is parked in WFE after all the initialization. Core1 does not directly participate in the boot flow, and is simply parked in a WFI.

Power down these R5 cores (and the associated RTI timer resources that were indirectly powered up) after starting up ATF on A53 by using the appropriate SYSFW API in release_resources_for_core_shutdown(). This allows these Main R5F cores to be further controlled from the A53 to run regular applications.
