The PLL4 can be used by ROM code as the source clock of USB PHYC and,
in this case, the PLL4 configuration must be preserved
with pll4_preserve to avoid USB disturbance.
This patch also adds an error when the clock tree PLL4 configuration
is not the PLL4 configuration used by ROM code; this error allows to
detect a invalid clock tree.
This commit corrects the coverity issue 343023.
