3rdparty/fsp: Update to current master again

We had to role the `fsp` submodule back for a minute due to a regression
with the Coffee Lake binary. Intel silently mixed FSP 2.1 features into
the Coffee Lake FSP which is supposed to be FSP 2.0. With the stack and
heap usage partitioned for FSP using coreboot's stack (config FSP_USES_
CB_STACK), it works again.

To make this even messier: We already selected this Kconfig option for
Whiskey Lake, which is supposed to use the very same FSP binary. So with
either submodule pointer, something was always broken :-/
