arm64: dts: qcom: qcs6490-rb3gen2: Declare GCC clocks protected

The SC7280 GCC binding describes clocks which, due to the difference in
security model, are not accessible on the RB3gen2 - in the same way seen
on QCM6490.

Mark these clocks as protected, to allow the board to boot. In contrast
to the present QCM6490 boards GCC_EDP_CLKREF_EN is left out, as this
does not need to be "protected" and is used on the RB3Gen2 board.
