Subject: [PATCH] configs: arm64: k3-am625-sk: Add VTM memory region

Add the memory region for VTM to the device-specific config
file. This fixes a runtime exception when the kernel accesses
that memory region:

<snip>
Unhandled data read at 0xb00308(4)

FATAL: unhandled trap (exception class 0x24)
