Update RPi3 firmware to fix startup on newer kit

Browse Source 
With the current firmware being pulled for the RPi3, recent revisions of
the RPi hardware, such as the 3 B+ will fail to boot.

The issue is exhibited as when RPi 3 B+ receives power and attempts to
boot, the power LED will turn off and the ACT LED will flash 8 times.
According to elinux.org troubleshooting guide[0] this correlates to an
SDRAM initialisation error that can be fixed by updating the firmware.

After updating this firmware the power light stays on, and UBoot can be
seen booting.
