[U-Boot] [U-Boot, 12/15] rockchip: board: puma-rk3399: update .its file to use new features

[Philipp Tomsich]

> 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.
