ARM: dts: meson8: correct uart_B and uart_C clock references

[ Upstream commit 98b503c7fb13a17a47d8ebf15fa8f7c10118e75c ]

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.

This was originally reported by Hans-Frieder Vogt for Meson8b [0], but
the same bug is also present in meson8.dtsi
