Hi Philipp,
Here are UniPhier SoCs updates for v4.14.
- Remove old SoC support
- Remove useless macros
Masahiro Yamada (2):
reset: uniphier: remove sLD3 SoC support
reset: uniphier: do not use per-SoC macro for system reset block

This SoC is too old. It is difficult to maintain any longer.

This macro turned out not so useful as I had expected.
Hardware engineers said they would change reset bit assignments for
every SoC going forward. This means we can not share the macros
among SoCs. Just use primitive macros.
