[PATCH 3/5] riscv: dts: spacemit: Add the K1 APB timer

[Troy Mitchell <troy.mitchell@linux.spacemit.com>]

Describe the first APB timer block and its counter 0 interrupt so it can
provide a shared clockevent. Connect its functional and bus clocks and
reset, and select the oscillator-derived 1 MHz input for a stable counter
rate independent of the PLLs.
