[PATCH v2 6/8] MIPS: Loongson64: dts: ls7a-pch: Bind UART nodes to miscellaneous clock

[Rong Zhang]

The Loongson-7A's UART controllers are driven by an internal 50MHz clock
source called miscellaneous clock. The clock is nonconfigurable for
board manufacturer and software.

Therefore, the LS7A UART nodes don't need to be fixed up by
lefi_fixup_fdt_serial(), and can safely use clocks nodes rather than
clock-frequency ones.
