Subject: [PATCH] ARM: dts: meson8: correct uart_B and uart_C clock references

On Meson8 uart_B and uart_C do not work, because they are relying on
incorrect clocks. Change the references of pclk to the correct CLKID
(UART1 for uart_B and UART2 for uart_C), to allow use of the two uarts.

Fixes: 57007bfb5469 ("ARM: dts: meson8: Fix the UART device-tree schema validation")
Reported-by: Hans-Frieder Vogt <hfdevel@....net> # for meson8b.dtsi
