Subject: [PATCH 02/15] ARM: dts: ls1021a: correct node name "timer0" to
 'rtc' and remove reg-names

Rename 'time0' to 'rtc' to fix below DTB_CHECK warning:
  timer0@...0000: $nodename:0: 'timer0@...0000' does not match '^rtc(@.*|-([0-9]|[1-9][0-9]+))?$

Remove undocument and unused property 'reg-names' to fix below warning:
  rtc@...0000: Unevaluated properties are not allowed ('reg-names' was unexpected)
