grub: Use regexp in grub.cfg for smbios product name of rpi4/rpi5

- Latest u-boot has removed smbios model info for raspberrypi devices - So, grub gets the full product name reported by the firmware (eg. "Raspberry Pi 4 Model B Rev 1.5" / "Raspberry Pi 5 Model B Rev 1.0") - We use regexp to be able to support different revisions of the devices Signed-off-by: Dimitrios Poulios <[email protected]>
