[PATCH v3] i2c: busses: convert to devm_platform_ioremap_resource

From: Dejin Zheng
Date: Thu Apr 09 2020 - 09:52:34 EST

use devm_platform_ioremap_resource() to simplify code, it
contains platform_get_resource and devm_ioremap_resource.

v2 -> v3:
- squash all 24 patches into one by Wolfram's suggestion.
v1 -> v2:
- delete 4 patches of can not be sent by gmail server.
then, has 24 patches.
