Simplify this function implementation by using the wrapper function “devm_platform_ioremap_resource” instead of calling the functions “platform_get_resource” and “devm_ioremap_resource” directly.
* Thus reduce also a bit of exception handling code here. * Delete the local variable “res”.
This issue was detected by using the Coccinelle software.

v2: Further changes were requested by Radhey Shyam Pandey. https://lore.kernel.org/r/CH2PR02MB700047AFFFE08FE5FD563541C78E0@CH2PR02MB7000.namprd02.prod.outlook.com/
* Updates for three modules were split into a separate patch for each driver. * The commit description was adjusted.
