soc/amd/{cezanne,picasso}: Escape PSP_VERSTAGE_FILE default

If we don't escape the $ then the actual $(obj) path will be written
into the .config file. With this change `$(obj)` is written into the
.config file. The Makefile then does:

    PSP_VERSTAGE_FILE=$(call strip_quotes,$(CONFIG_PSP_VERSTAGE_FILE))

Since this is a recursive assignment the $(obj) will be expanded at that
point.

This change makes it easier to compare full .config files.
