clk: qcom: gcc-sc8280xp: Set delay for Venus CLK resets
Some Venus resets may require more time when toggling. Describe that.
The value was obtained on a best-guess basis: msm-5.4 being the base
kernel for this SoC and 8280 being generally close to 8350 which is known
to require a higher delay [1].
