[PATCH v12 4/4] dt-bindings: timer: dwc: Update resets property items

[dongxuyang]

From: Xuyang Dong <dongxuyang@xxxxxxxxxxxxxxxxxx>

The DesignWare DW_apb_timers IP has two active-low reset inputs:
presetn resets the register interface logic in the pclk (bus) domain,
and timer_N_resetn resets the counter/timer logic in the timer_N_clk
domain. The existing snps,dw-apb-timer binding only describes one.

Update snps,dw-apb-timer binding to allow up to two reset lines,
matching the hardware capabilities of the DesignWare IP family.
