As per the i.MX51 Reference Manual add an entry for the
'tigerp' region in the device tree.
This is needed for accessing the ARM_GPC register to set the
DBGEN bit, so that the debug clocks can be turned on.

Add a label for the PMU node so that the board dts may be able to
pass the 'secure-reg-access' property like this:
&pmu {
secure-reg-access;
};
This also makes it consistent with the PMU node in imx6qdl.dtsi

* [PATCH v4 6/6] ARM: mx5: Set the DBGEN bit in ARM_GPC register

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.
