X-Git-Tag: v6.18-rc1~147^2~12^2

riscv: dts: spacemit: uart: remove sec_uart1 device node

sec_uart1 is not available from Linux, and no clock is implemented in
CCF framework, thus 'make dtbs_check' will pop up this warning message:

  serial@f0612000: 'clock-names' is a required property

Removing the node from device tree to silence the DT check warning.
