drm/v3d: Use V3D_SMS registers for power on/off and reset on V3D 7.xHEADdrm-misc-next
In addition to the standard reset controller, V3D 7.x requires configuring
the V3D_SMS registers for proper power on/off and reset. Add the new
registers to `v3d_regs.h` and ensure they are properly configured during
device probing, removal, and reset.
This change fixes GPU reset issues on the Raspberry Pi 5 (BCM2712).
Without exposing these registers, a GPU reset causes the GPU to hang,
stopping any further job execution and freezing the desktop GUI. The same
issue occurs when unloading and loading the v3d driver.
