plat-versal2: conf: Add maximum size of the DTB

The DTB size for the AMD platform is larger and does not fit into the

plat-versal2: conf: Add maximum size of the DTB

The DTB size for the AMD platform is larger and does not fit into the
default size, leading to failure or panic at boot time due to size
issues.

Thus setting an explicit maximum size for the Device Tree Blob to
allow safe modifications. This ensures there is enough space when
appending or editing nodes/properties in the DTB.

drivers: amd: Add PS GPIO Support

Add PS GPIO Driver support for AMD Platforms.

The PS GPIO Controller is managed through the PS subsystem and
can operate in either the Secure World or the Non-Secure World.
The driver utilizes the Device Tree Blob (DTB) to determine whether the
PS GPIO Controller should be supported in the Secure World.
