The commit cefc8be82403cf ("Consolidate bust_spinlocks()") kept
the s390-specific implementation because of the absence of CONFIG_VT.
In fact, the only difference was calling console_unblank() instead of
unblank_screen().
The common implementation in lib/bust_spinlocks.c started to call
unblank_screen() explicitly since the commit b61312d353da187
("oops handling: ensure that any oops is flushed to the mtdoops
console").
As a result, the custom implementation is not longer necessary.
And we could get all the other improvements of the common
implementation for free.
