Merge branch 'omap1/multiplatform-prep' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc into arm/multiplatform

This is the full series for converting OMAP1 to multiplatform, rebased
from my 2019 attempt to do the same thing. The soc tree contains simpler
patches to do the same for iop32x, ixp4xx, ep93xx and s3c24xx, which
means we are getting closer to completing this for all ARMv5 platforms
(I have patches for PXA, which is the last one remaining).

Janusz already tested the branch separately and did the missing work
for the common-clk conversion after my previous approach was broken.

Aaro found one regression during additional testing, this is fixed now.
