[PATCH i-g-t v4 2/4] tests/intel/kms_pm_dc: Update test duration to 4 seconds

[Naladala, Ramanaidu]

Hi Suraj,

We need to simulate the scenario of extended vblank. Keeping CI 
execution time in mind, we have set the sequence for 4 seconds. For the 
first 2-3 seconds, we run at X refresh rate and then change the refresh 
rate in between to emulate extended vblank for the remaining 4 seconds.
