Converts rtc/faraday,ftrtc01.txt to yaml.
This permits to detect some missing properties: reg, resets, interrupts

+    description: when present should contain clock references to the
+                 PCLK and EXTCLK clocks. Faraday calls the later CLK1HZ and
+                 says the clock should be 1 Hz, but implementers actually seem
+                 to choose different clocks here, like Cortina who chose
+                 32768 Hz (a typical low-power clock).
Normal formatting is 2 space indent.

Split to use 'items' like PCI.
