drm/amd/display: Add inbox0 HW lock helpers for DCN35
Add dcn35_dmub_hw_control_lock() and dcn35_dmub_hw_control_lock_fast(),
a SW lock mechanism to prevent racing between driver and FW.
The helpers are not wired into dcn35_funcs/dcn351_funcs yet, so there is
no functional change: DCN3.5/3.5.1/3.6 keep using the existing inbox1
lock path. Enabling them will come in a follow-up patch.
