msm-fixes for v6.3-rc2

- Fix for possible invalid ptr free in submit ioctl syncobj cleanup path.
- Synchronize GMU removal in driver teardown path
- a5xx preemption fixes
- Fix runpm imbalance at unbind
- DPU hw catalog fixes:
 - set DPU_MDP_PERIPH_0_REMOVED for sc8280xp as this is another chipset
   where the PERIPH_0 block of registers is not there
 - fix the DPU features supported in QCM2290 by comparing it with the
   downstream device tree
 - fix the length of registers in the sc7180_ctl from 0xe4 to 0x1dc
 - fix the max mixer line width for sm6115 and qcm2290 chipsets in the
   DPU catalog
 - fix the scaler version on sm8550, sc8280xp, sm8450, sm8250, sm8350
   and sm6115. This was incorrectly populated on the SW version of the
   scaler library and  not the scaler HW version
 - Drop dim layer support for msm8998 as its not indicated to be
   supported in the downstream DTSI
 - fix the DPU_CLK_CTRL bits for msm 8998 sspp blocks
 - Use DPU_CLK_CTRL_DMA* prefix instead of DPU_CLK_CTRL_CURSOR*
   for all chipsets for the DMA sspp blocks
 - fix the ping-pong block base address for sc7280 in the DPU HW catalog
- Fix stack corruption issue in the dpu_hw_ctl_setup_blendstage() function
  as it was causing a negative left shift by protecting against an invalid
  index
- Clear the DSPP reservations in dpu_rm_release(). This was missed out and
  as as result the DSPP was not released from the resource manager global
  state.
