>From the hardware perspective, the actual pclk of the AO uarts
is the corresponding clkc_ao uart gate, not the main clock controller clk81.
This was not problem so far, because the uart_gate had
the CLK_IGNORE_UNUSED flag, which kept the gate open.
We plan to remove the CLK_IGNORE_UNUSED flag in another patch,
but before doing that, we need to fix the clock in the DTS file.
