dev, arm: fix error class-memaccess with GCC >= 8.1
From GCC 8.1 on GCC issues a warning when using memset et al on structs and
classes. With the way gem5 builds, this actually prevents successful
builds.
Instead of using a pointer with SCSIReply as type, we cast to a void
pointer to avoid the message. On the way we wrap the memset call into a
method of SCSIReply called reset for better code readability.
