[PATCH 2/2] dt-bindings: rtc: Add bindings for Ricoh rs5c372

[Pavel Modilaynen <pavel.modilaynen@axis.com>]

From: Pavel Modilaynen <pavelmn@axis.com>

Create new DT bindings yaml file for Ricoh rs5c372 driver
since adding property support naturally deserves it.
Place a description of this property: ricoh,trim.

+      Raw value of Oscillation Adjustment Register (0x7) which changes
+      time counts of 1 second. Normally, the second counter is incremented
+      once per 32768 clock pulses. The value causes to increment
+      decrement time counts when second digits read 00, 20, 40 seconds
+      (R222[13] can operate on 00 seconds if MSB set).
+      See datasheets for details.
