clk: tegra124: Add init data for dsi lp clocks
Set the parent of the dsi lp clocks to pll_p and the rate to 68MHz. The default parent is clk_m and rate is 12MHz, this is too slow to receive data from the peripheral. Per NVidia HW engineers, the optimal rate is 70MHz, but 68MHz will suffice. Signed-off-by: Sean Paul <seanpaul@chromium.org> Signed-off-by: Peter De Schrijver <pdeschrijver@nvidia.com>
