Merge branch 'master' of https://source.denx.de/u-boot/custodians/u-boot-sunxi

a bit delayed, the first batch of the sunxi pull request for this cycle.
This is mostly collecting some patches that were lying around for a
while, plus some recent fixes. Nothing too exciting at this point, but
of course they should be merged nevertheless.
There is the much bigger F1C100s SoC support coming up, which I hope to
be able to send in the next few days, along with the removal of sunxi's
lowlevel_init usage.

Compile tested for all 159 sunxi boards, plus briefly tested on BananaPi
M1, OrangePi Zero, Pine64 and Pine-H64.
