drm/tegra: Set static Fmax for suspend frequency

Browse Source 
The suspend_freq is a fixed value for devfreq core, while the
resume_freq will be changed dynamically based on the last previous
updated frequency value of the device.

When device is put into suspend mode, devfreq core will update the
resume frequency with the suspend frequency. Therefore, when the device
is resumed back again, it will run at suspend_freq.

Forcelly set the suspend_freq as Fmax so that device will run at Fmax
when it is resumed back.
