Standardize usage of RTC memory bridge capacitor for Pixhawk series

LorenzMeier commented 8 years ago

All Pixhawk series boards should buffer the RTC RAM. We have now hard fault logging:

[boot] Fault Log info File No 3 Length 3257 flags:0x00 state:1
[boot] Fault Log is Armed
[hardfault_log] Fault Log is Armed

Which means even if the whole OS crashes it will power-cycle, offer the last system state for an in-flight restore and then once the system is back up online write the fault to the microSD for post-flight analysis.

Pixhawk 1 and Pixhawk 2 have the buffer power supply, and so should any other board in the series.
