media: intel/ipu6: Don't re-allocate memory for firmware
The ipu6 driver allocated vmalloc memory for the firmware if
request_firmware() somehow managed not to use vmalloc to allocate it.
Still how the memory is allocated by request_firmware() is not specified
in its API, so be prepared for kmalloc-allocated firmware, too. Instead of
allocating new vmalloc-backed buffer for the firmware, obtain the pages
from virtual addresses instead.

media: intel/ipu6: add IPU6 buttress interface driver
The IPU6 buttress is the interface between IPU device (input system and
processing system) with rest of the SoC. It contains overall IPU hardware
control registers, these control registers are used as the interfaces with
the Intel Converged Security Engine and Punit to do firmware
authentication and power management.
