From: Sasha Neftin <sasha.neftin@intel.com>

[ Upstream commit c80a29f0fe9b6f5457e0788e27d1110577eba99b ]

Replace usleep_range() method with udelay() method to allow atomic contexts
in low-level MDIO access functions.

The following issue can be seen by doing the following:
$ modprobe -r bonding
$ modprobe -v bonding max_bonds=1 mode=1 miimon=100 use_carrier=0
$ ip link set bond0 up
$ ifenslave bond0 eth0 eth1
