Because H3 ES1 becomes an increasing maintenance burden and was only
available to a development group, we decided to remove upstream support
for it. It doesn't even boot since v6.3-rc1. Here are the patches to
remove the architecture and core bits. Other driver changes will be sent
individually. Review tags have been gathered before during an internal
discussion. Only change since the internal version is a plain rebase to
v6.3-rc1. A branch with all removals is here:

Good bye ES1.*, I expect that Geert will queue the patches as usual.

At your service, queuing in renesas-pinctrl-for-v6.4.
