rockchip: Drop bootstage stash in TPL and SPL for rockpro64

Unfortunately the IRAM used to stash the bootstage records in TPL
becomes inaccessible after SPL runs. Presumably this is because of ATF
taking it over.

We could move the stash to another address in SPL, before passing it to
U-Boot proper. But it seems easier to wait until we have support for
standard passage[1] which should not be too far away.

For now, disable it in TPL and SPL.
