This commit updates the .its file for the RK3399-Q7 to use the new features and demonstrates how to use those: * it marks the ATF as the 'firmware' * it tracks the OS-type for U-Boot and ATF * it loads the PMU (M0) firmware to DRAM and records the location to /fit-images (where our ATF reads it from) With the handoff of the next-stage FDT to ATF in place, we can now use this to pass information about the load addresses and names of each loadables to ATF: now we can load the M0 firmware into DRAM and avoid overwriting parts of the SPL stage. This is achieved by changing our .its-file to use an available area of DRAM as the load-address.
