drm/panthor: validate firmware interface structure sizes

In the Linux kernel, the following vulnerability has been resolved:

drm/panthor: validate firmware interface structure sizes

iface_fw_to_cpu_addr() only checks that the firmware-provided MCU virtual
address points inside the shared section. The returned pointer is later
used as a full firmware interface structure, so accepting an address near
the end of the shared section can still lead to out-of-bounds accesses.

Pass the expected object size to iface_fw_to_cpu_addr() and reject ranges
that do not fit entirely in the shared section.
