from stable-5.10.76

bugzilla: 182988 https://gitee.com/openeuler/kernel/issues/I4IAHF

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=6418508a3ac2a85a48d097f478566708a4f43087

--------------------------------

[ Upstream commit 639e298f ]

Update the HW MAC initialization flow. Do not gate DMA clock from
the modPHY block. Keeping this clock will prevent dropped packets
sent in burst mode on the Kumeran interface.
