clk: qcom: clk-rcg2: Take clock boundaries into consideration for gfx3d

Browse source

The gfx3d clock is hand-crafting its own clk_rate_request in
clk_gfx3d_determine_rate to pass to the parent of that clock.

However, since the clk_rate_request is zero'd at creation, it will have
a max_rate of 0 which will break any code depending on the clock
boundaries.

That includes the recent commit 948fb0969e ("clk: Always clamp the
rounded rate") which will clamp the rate given to clk_round_rate() to
the current clock boundaries.

For the gfx3d clock, it means that since both the min_rate and max_rate
fields are set at zero, clk_round_rate() now always return 0.

Let's initialize the min_rate and max_rate fields properly for that
clock.
