[][kernel][common][eth][Refactor the link polling mechanism to improve CPU usage in the USXGMII/SGMII]

[Description]
Refactor the link polling mechanism to improve CPU usage in the
USXGMII/SGMII.

The busy-wait delay functions (udelay/mdelay) may waste CPU resources.
Therefore, we need to switch to using usleep_range() instead. However,
the usleep_range function cannot be used in interrupt contexts, such as
in timer tasks. Consequently, we need to change timer tasks to
delayed_work and replace all instances of udelay with usleep_range().

Without this patch, the link polling mechanism of USXGMII/SGMII may
waste CPU resources.
