    arm64: dts: amlogic: gx: correct hdmi clocks
    
    [ Upstream commit 0602ba0dcd0e76067a0b7543e92b2de3fb231073 ]
    
    The clocks provided to HDMI tx are not consistent between gx and g12:
    * gx receives the peripheral clock as 'isfr' while g12 receives it as
      'iahb'
    * g12 gets the HDMI system clock as 'isfr' but gx does not even get it.
      It surely needs that clock since the driver is directly poking around
      the clock controller's registers for that clock.
    
    Align gx SoCs with g12 and provide:
     * the HDMI peripheral clock as 'iahb'
     * the HDMI system clock as 'isfr'
