[PULL 43/63] hw/cxl: Line length reductions

["Michael S. Tsirkin" <mst@redhat.com>]

From: Jonathan Cameron <Jonathan.Cameron@huawei.com>

Michael Tsirkin observed that there were some unnecessarily
long lines in the CXL code in a recent review.
This patch is intended to rectify that where it does not
hurt readability.
