brcm2708: Update brcm2708-gpu-fw package

Problem - rapsberry pi 3 b/b+ does not boot with bcm2710 images!

How Raspberry Pi boots Actualy?

When Raspberry is switched on GPU is activated.
1. GPU execute First stage bootloader from ROM.
First stage bootloader mount the FAT boot partition on the SD card
and execute second stage bootloader (bootcode.bin).
2. Second stage bootloader (bootcode.bin) activate SDRAM.
Load the GPU firmware (start.elf).
3. GPU firmware (start.elf)
  a) display Rainbow splash.
  b) read firmware configuration file config.txt and
     split the RAM using fixup.dat.
  c) loads a cmdline.txt
  d) enables the CPU.
  e) loads the kernel image configurable via config.txt

In your target/linux/brcm2708/image/config.txt
 493 ## kernel (string)
 494 ##     Alternative name to use when loading kernel.
 495 ##
 496 #kernel=""
it is not configured!

But in your target/linux/brcm2708/image/Makefile
  75   KERNEL_IMG := kernel8.img
  76   DEVICE_TITLE := Raspberry Pi 3B/3B+
you have kernel8.img

GPU Firmware search order by default for a PI 3 is:
kernel8.img if found boot in 64 bit mode
kernel8-32.img if found boot in 32 bit mode
kernel7.img if found boot in 32 bit mode
kernel.img if found boot in 32 bit mode

But a PI 2 will start the search from kernel7.img and
a PI 1 only looks for kernel.img.

Оbviously the kernel has been found.
But something goes wrong and the device is restarted.

In your package/kernel/brcm2708-gpu-fw/Makefile
  11 PKG_NAME:=brcm2708-gpu-fw
  12 PKG_VERSION:=2017-08-08
  13 PKG_RELEASE:=e7ba7ab135f5a68b2c00a919ea9ac8d5528a5d5b
boot loader is 10 monts old.

In conclusion, the best way to solve the problem is
to update the boot loader!

Fixup_cd.dat and start_cd.elf files are not necessary.
These are used when GPU memory is set to 16 MB, which disables
some GPU features.
I did not remove them just in case!

cheers
