drm/panthor: fix firmware control interface bounds checks

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

drm/panthor: fix firmware control interface bounds checks

panthor_init_cs_iface() and panthor_init_csg_iface() validate firmware
control interface offsets with 32-bit arithmetic and the size of the host
wrapper structures. The offsets are derived from firmware-provided strides,
so the arithmetic can wrap before the bounds check, and the host wrapper
size is not the size of the firmware control interface being mapped.

Use 64-bit arithmetic for the computed offsets and validate against the
actual firmware control interface structure sizes with subtraction-based
bounds checks. Also validate that the shared section is large enough for
the global control interface before using it.
