An earlier commit defined an alias for all SPI controllers found on the
RK3399, so there's no need to duplicate the aliases in helios64's device

There are 6 SPI controllers on RK3399 and they are all numbered in the
TRM, so let's add the appropriate aliases to the main DTSI so that any
RK3399-based board doesn't need to define the aliases themselves to
benefit from stable SPI indices in userspace.

Add missing cache information to the Rockchip RK3399 SoC dtsi.  The specified
values were derived by hand from the cache size specifications available from
the RK3399 datasheet;  for future reference, here's a brief summary:

  - Each Cortex-A72 core has 48 KB of L1 instruction cache and
    32 KB of L1 data cache available, four-way set associative
  - Each Cortex-A53 core core has 32 KB of instruction cache and
    32 KB of L1 data cache available, four-way set associative
  - The big (A72) cluster has 1 MB of unified L2 cache available
  - The little (A53) cluster has 512 KB of unified L2 cache available

This patch allows /proc/cpuinfo and lscpu(1) to display proper RK3399 cache
information, and it eliminates the following error in the kernel log:

  cacheinfo: Unable to detect cache hierarchy for CPU 0

While there, add a couple of somewhat useful comments, which may help a bit
anyone going through the RK3399 SoC dtsi.
