hwmon: (xgene) Fix ioremap and memremap leak
Description

In the Linux kernel, the following vulnerability has been resolved: hwmon: (xgene) Fix ioremap and memremap leak Smatch reports: drivers/hwmon/xgene-hwmon.c:757 xgene_hwmon_probe() warn: 'ctx->pcc_comm_addr' from ioremap() not released on line: 757. This is because in drivers/hwmon/xgene-hwmon.c:701 xgene_hwmon_probe(), ioremap and memremap is not released, which may cause a leak. To fix this, ioremap and memremap is modified to devm_ioremap and devm_memremap. [groeck: Fixed formatting and subject]
