drm: bochs: fix warnings

Regular nightly randconfig build testing discovered these warnings:

drivers/gpu/drm/bochs/bochs_drv.c:100:12: warning: 'bochs_pm_suspend' defined but not used [-Wunused-function]
drivers/gpu/drm/bochs/bochs_drv.c:117:12: warning: 'bochs_pm_resume' defined but not used [-Wunused-function]

Fix these by adding the same condition that SET_SYSTEM_SLEEP_PM_OPS()
uses.
