Subject: [PATCH] thermal/drivers/thermal_mmio: Use devm_platform_get_and_ioremap_resource()

From: ye xingchen <ye.xingchen@....com.cn>

Convert platform_get_resource(), devm_ioremap_resource() to a single
call to devm_platform_get_and_ioremap_resource(), as this is exactly
what this function does.
