drm/vc4: Add support for branching in shader validation.

We're already checking that branch instructions are between the start
of the shader and the proper PROG_END sequence.  The other thing we
need to make branching safe is to verify that the shader doesn't read
past the end of the uniforms stream.

To do that, we require that at any basic block reading uniforms have
the following instructions:

load_imm temp, <next offset within uniform stream>
add unif_addr, temp, unif

The instructions are generated by userspace, and the kernel verifies
that the load_imm is of the expected offset, and that the add adds it
to a uniform.  We track which uniform in the stream that is, and at
draw call time fix up the uniform stream to have the address of the
start of the shader's uniforms at that location.

(For example, they might request a copy of the modified ioctl argument

However, blindly copying over the target address may also lead to a

successfully. This is important in order to avoid an ABI break when

drm/nouveau/clk/gm20b: add glitchless and DFS support

This patch adds support for advanced features supported by the

updated without disabling the PLL first if the SYNC_MODE bit of the CFG
register is set.

More significantly, DFS allows the PLL to monitor the actual input
voltage and to dynamically lower the output frequency accordingly. This
allows the clock to be more tolerant of lower voltages.

These improvements are only supported for Tegra speedos >= 1.

Also add the voltage table that is suitable for GM20B's NAPLL. This
change needs to be done atomically for the right voltages to be used by
the clock driver.
