Subject: [PATCH v1 0/9] Fix Allwinner D1 boot regression

Hi Anup,

As described in the thread below[1] I haven't been able to boot my
boards based on the Allwinner D1 SoC since 6.9 where you converted the
SiFive PLIC driver to a platform driver.

This is clearly a regression and there haven't really been much progress
on fixing the issue since then, so here is the revert that fixes it.

If no other fix is found before 6.11 I suggest we apply this.
