drm/msm/a5xx: fix setting of the CP_PREEMPT_ENABLE_LOCAL register

Browse source

[ Upstream commit a7a4c19c36 ]

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.
