PATCH 1/2 ARM: dts: imx6sx-sdb: update TX D_CAL for USBPHY

We need to change trimming value (as a percentage) of the 17.78mA TX reference current for better signal quality. With this change, we can patch the eye-diagram test on this board.

s/patch/pass? I just want to confirm this is a typo, and can fix it up when applying.
