package/rpi-firmware: bump

Yet another bump for the Raspberry Pi firmware:
  - HDMI: EDID override; HDCP fix; add command to control power to HDMI phy;
        fixes to mode selection
  - GPU: enable use of HW cursor; fix for GLES FFT compliance; fix scaling;
        remove arbitrary restrictions on output sizes
  - video-decode: better handle corrupted h264 streams, better allocate memory
  - misc: choose composite video when HDMI is not plugged
