[U-Boot] [PATCH 07/15] ARM: DTS: stm32: Enable Clock driver for stm32h743

[patrice.chotard at st.com]

From: Patrice Chotard <patrice.chotard at st.com>

Add RCC clock driver node and update all clocks phandle
accordingly.

By default, on kernel side, all clocks was temporarly
configured as a phandle to timer_clk waiting for a RCC
clock driver to be available.
On U-boot side, we now have a dedicated RCC clock driver, we
can configured all clocks as phandle to this driver.

All this binding update will be available soon in a kernel tag,
as all the bindings have been acked by Rob Herring [1].
