From: Hou Zhiqiang <B48286-KZfg59tc24xl57MIdRCFDg@public.gmane.org>

Add aliases for eSPI device node to assign the alias id to the
bus number of spi_master.

For the platforms used the device tree, the bus numbers are
dynamically assigned and are not predictable. However, sometimes
it must be figured out, e.g. using mtdparts in cmdline to specify
the layout of spi flash.
