Subject: [PATCH] crypto: hisilicon: Fix misuse of GENMASK macro

Arguments are supposed to be ordered high then low.

Fixes: c8b4b477079d ("crypto: hisilicon - add HiSilicon HPRE accelerator")
Signed-off-by: Rikard Falkeborn <rikard.falkeborn@...il.com>

Spotted when trying to introduce compile time checking that the order
of the arguments to GENMASK are correct [0]. I have only compile tested
the patch.
