4.4 Stable: Revert "usb: chipidea: imx: enable CI_HDRC_SET_NON_ZERO_TTHA"

[Martin Fuzzey <mfuzzey@xxxxxxxxxxx>]

Hello,

Please apply the commit 1bc7da87c7410c6990c3251589e3854e64c55af2 (Revert 
"usb: chipidea: imx: enable CI_HDRC_SET_NON_ZERO_TTHA")
to the 4.4 stable tree.

Although not mentionned in the original revert commit message this fixes 
"choppy" USB audio playback on i.MX53.

The patch applies cleanly to 4.4.47 and audio playback now works 
correctly on my i.MX53 board.

(By my understanding of Documentation/stable_kernel_rules.txt, a simple 
email like this should be sufficient for "Option 2").

Thanks,

Martin
