net: hns: All ports can not work when insmod hns ko after rmmod.
There are two test cases:
1. Remove the 4 modules:hns_enet_drv/hns_dsaf/hnae/hns_mdio,
and install them again, must use "ifconfig down/ifconfig up"
command pair to bring port to work.
This patch calls phy_stop function when init phy to fix this bug.
2. Remove the 2 modules:hns_enet_drv/hns_dsaf, and install them again,
all ports can not use anymore, because of the phy devices register
failed(phy devices already exists).
Phy devices are registered when hns_dsaf installed, this patch
removes them when hns_dsaf removed.
The two cases are sometimes related, fixing the second case also requires
fixing the first case, so fix them together.
