Subject: Revert "usb: chipidea: imx: enable CI_HDRC_SET_NON_ZERO_TTHA"
From: Peter Chen <peter.chen@xxxxxxx>
commit 1bc7da87c7410c6990c3251589e3854e64c55af2 upstream.
This reverts commit e765bfb73ff7.
In the most of cases, we only use one transaction per frame and the
frame rate may be high, If the platforms want to support multiple
transactions but less frame rate cases like [1] and [2], it can set
"non-zero-ttctrl-ttha" at dts.
