[PATCH] media: staging: ipu7: declare firmware files with MODULE_FIRMWARE

[German <germanpapulindez@gmail.com>]

drivers/staging/media/ipu7/ipu7.h already defines the three firmware
blob names the driver can request at runtime depending on the SoC
generation:

    IPU7_FIRMWARE_NAME    "intel/ipu/ipu7_fw.bin"
    IPU7P5_FIRMWARE_NAME  "intel/ipu/ipu7ptl_fw.bin"
    IPU8_FIRMWARE_NAME    "intel/ipu/ipu8_fw.bin"

but ipu7.c never declares them via MODULE_FIRMWARE(), so tools that
rely on modinfo to discover firmware dependencies (most initramfs/
initrd generators, e.g. mkinitcpio, dracut) can't automatically
include the right blob for this driver.

  $ modinfo -k $(uname -r) intel_ipu7 | grep -iE "firmware|filename"
  filename:       /lib/modules/7.2.2-arch1-1/kernel/drivers/staging/media/ipu7/intel-ipu7.ko.zst

No "firmware:" line is printed at all, even though the driver does
load one of the three blobs above at probe time (confirmed separately
via dmesg on real Lunar Lake/IPU7 hardware - "firmware cpd file:
intel/ipu/ipu7_fw.bin" - so the dependency is real, just not declared
to modinfo).

This is low priority/cosmetic on distros that ship the full
linux-firmware package unconditionally (as Arch does), but matters
for anyone building a minimal initramfs, or packaging this driver
for a distro that only pulls in firmware modinfo declares.
