[PULL 10/20] via-ide: allow guests to write to PCI_CLASS_PROG

Subject: [PULL 10/20] via-ide: allow guests to write to PCI_CLASS_PROG
Date: Tue, 17 Mar 2020 19:23:19 -0400

From: Mark Cave-Ayland <address@hidden>

MorphOS writes to PCI_CLASS_PROG during IDE initialisation to place the
controller in native mode, but thinks the initialisation has failed
because the native mode bits aren't set when reading the register back.
