clk: bcm: rpi: Maximize V3D clock

Although minimizing the clock rate is the best for most scenarios, as
stated in commit 4d85abb0fb8e ("clk: bcm: rpi: Enable minimize for all
firmware clocks"), when it comes to the GPU, it's ideal to have the
maximum rate allowed.

Add an option to maximize a firmware clock's rate when the clock is
enabled and set this option for V3D.
