From: Bjorn Andersson <quic_bjorande@xxxxxxxxxxx> [ Upstream commit 7c6bef576a8891abce08d448165b53328032aa5f ] 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.
