drm/amdgpu: Update SDMA firmware version check for user queue support

Browse Source 
This commit fixes a firmware version check for enabling user queue
support in SDMA v7.0. The previous version check (7836028) was
incorrect and could lead to issues with PROTECTED_FENCE_SIGNAL
commands causing register conflicts between MCU_DBG0 and MCU_DBG1.

Fixes: 8c011408ed ("drm/amdgpu/sdma7: add ucode version checks for userq support")
