drm/msm/adreno: fix a743 and a740 cx mem init
Disable the call to qcom_scm_gpu_init_regs() for a730 and a740
after init failures on the HDK8550 and HDK8450 platforms:
msm_dpu ae01000.display-controller: failed to load adreno gpu
msm_dpu ae01000.display-controller: failed to bind 3d00000.gpu (ops a3xx_ops [msm]): -5
msm_dpu ae01000.display-controller: adev bind failed: -5
While debugging, it happens the call to:
qcom_scm_gpu_init_regs(QCOM_SCM_GPU_ALWAYS_EN_REQ)
returns -5 and makes the gpu fail to initialize.
Remove the scm call since it's not done downstream either and
works fine without.
