On i.MX51/i.MX53 it is necessary to set the DBGEN bit in ARM_GPC register in order to turn on the debug clocks. The DBGEN bit of ARM_GPC register has the following description in the i.MX53 Reference Manual: "This allows the user to manually activate clocks within the debug system. This register bit directly controls the platform's dbgen_out output signal which connects to the DAP_SYS to enable all debug clocks. Once enabled, the clocks cannot be disabled except by asserting the disable_trace input of the DAP_SYS." Based on a previous patch from Sebastian Reichel.
