[U-Boot] [PATCH 1/7] mpc83xx: MPC837XEMDS: Initialize SerDes before negating PCIE reset signal

[Anton Vorontsov]

The SerDes initialization should be finished before negating the reset
signal according to the reference manual. This isn't an issue on real
hardware, but we'd better stick to the specifications anyway.
