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.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
