Subject: net: hisilicon: hns: Replace mdelay() with msleep()
Patch-mainline: v4.19-rc1
Git-commit: 89036f233a45d8d17c2de94850bd5e63f185da3d
References: bsc#1104353 FATE#326415

hns_ppe_common_init_hw() and hns_xgmac_init() are never
called in atomic context.
They call mdelay() to busily wait, which is not necessary.
mdelay() can be replaced with msleep().

This is found by a static analysis tool named DCNS written by myself.
