Use the new helper devm_platform_ioremap_resource() which wraps the
platform_get_resource() and devm_ioremap_resource() together, to
simplify the code.

Hello,

My impression[1] is that Thierry collects patches in bulk once or twice
per release cycle. The last two such bulks were between 5.2-rc6 and
5.2-rc7 and in the 5.2 merge window. So given we're at v5.3-rc5 now I
expect some action soon :-)

Ping..., 1 month passed, NOT sure what is the latest status.
