[U-Boot] [PATCH 1/2] ARM: tegra: reduce CSITE clock from 204M to 136M

From: Bryan Wu <pengw at nvidia.com>

The L4T kernel complains about a CSITE clock rate above 144MHz, presumably
because the HW is only characterized for a clock less than that. Adjust the
rate to 136MHz to avoid the warning and stay in spec.
