Rename the Rockchip RK356x SoC dtsi files and, consequently, adjust their
contents appropriately, to prepare them for the ability to specify different
CPU and GPU OPPs for each of the supported RK356x SoC variants.

The first new RK356x SoC variant to be introduced is the RK3566T, which the
Pine64 Quartz64 Zero SBC is officially based on. [1] Some other SBCs are
also based on the RK3566T variant, including Radxa ROCK 3C and ZERO 3E/3W,
but the slight trouble is that Radxa doesn't state that officially. Though,
it's rather easy to spot the RK3566T on such boards, because their official
specifications state that the maximum frequency for the Cortex-A55 cores is
lower than the "full-fat" RK3566's 1.8 GHz. [2][3][4]

These changes follow the approach used for the Rockchip RK3588 SoC variants,
which was introduced and described further in commit def88eb4d836 ("arm64:
dts: rockchip: Prepare RK3588 SoC dtsi files for per-variant OPPs"). Please
see that commit for a more detailed explanation.

No functional changes are introduced, which was validated by decompiling and
comparing all affected board dtb files before and after these changes. In
more detail, the affected dtb files have some of their blocks shuffled around
a bit and some of their phandles have different values, as a result of the
changes to the order in which the building blocks from the parent dtsi files
are included, but they effectively remain the same as the originals.
