This makes sure the clock tree setup for the dphy is not dependent on
other components.

Without this change bringing up the display can fail like

  kernel: phy phy-30a00300.dphy.2: Invalid CM/CN/CO values: 165/217/1
  kernel: phy phy-30a00300.dphy.2: for hs_clk/ref_clk=451656000/593999998 ~ 165/217

if LCDIF doesn't set up that part of the clock tree first. This was
noticed when testing the Librem 5 devkit with defconfig. It doesn't
happen when modules are built in.
