    drm/msm/a5xx: fix setting of the CP_PREEMPT_ENABLE_LOCAL register
    
    [ Upstream commit a7a4c19c36de1e4b99b06e4060ccc8ab837725bc ]
    
    Rather than writing CP_PREEMPT_ENABLE_GLOBAL twice, follow the vendor
    kernel and set CP_PREEMPT_ENABLE_LOCAL register instead. a5xx_submit()
    will override it during submission, but let's get the sequence correct.
