riscv: sifive_u: Remove handcrafted clock nodes for UART and ethernet
In the past we did not have a model for PRCI, hence two handcrafted
clock nodes ("/soc/ethclk" and "/soc/uartclk") were created for the
purpose of supplying hard-coded clock frequencies. But now since we
have added the PRCI support in QEMU, we don't need them any more.
