DCM means dynamic clock management, and it can dynamically slow down
or gate clocks during CPU or bus idle.
Add MCUSYS or bus related DCM drivers.
Enable MCUSYS or bus related DCM by default.

Distros (e.g. Buildroot and Android) can have different secure partition
layout.
This commit iterates the DPE metadata table and finds index (i) for the
first entry of the secure partition, connecting with the defined secure
partition number NUM_SP, so the last secure partition index is:
i + NUM_SP - 1
Instead of setting the certificate in hard code, dynamically enables the
certificate for the last secure partition base on calculated index.

The previous code used 64-bit registers as the target and source for
load and store operations on 32-bit hardware registers. In certain
cases (e.g., when using USART1 as the debug console), this could result
in deadlocks where the A35 gets stuck in a permanent loop due to test
conditions that are never fulfilled.
To resolve this issue, 32-bit registers are now used for these
operations.

External LLC is present on TC4 systems in MCN but it is not enabled in

On TC4, Gelas vs Non-Gelas CPUs have different bits to enable EXTLLC
so take care of that as well.

Reconfiguration of the PLL may be requested while some output dividers
are already enabled. To prevent setting a different frequency for these
enabled dividers, the driver will attempt to adjust the division factor
to achieve the initially requested rate.

The DFS can use the get_module_rate instead of assuming its parent
object is a PLL. It also has the advantage that the frequency will be
returned based on the hardware state of the PLL module.

Add the option to obtain the rate of an s32cc_dfs_div object. As in the
case of the PLL, the output divider of a DFS will return its targeted
frequency if the module is disabled and calculate the rate based on the
settings found in its registers if the module is turned on.
