Subject: [PATCH v2 02/12] drm/msm/dp: Fix the ISR_* enum values

ISR_HPD_IO_GLITCH_COUNT and ISR_HPD_REPLUG_COUNT are not in the correct
order. Swap them so that the ISR_* enum will have the correct values.

Also, correct the spelling for ISR_HPD_REPLUG_COUNT.

Fixes: 8ede2ecc3e5e ("drm/msm/dp: Add DP compliance tests on Snapdragon Chipsets")
