Subject: [PATCH] Add RTC feature for flashcart (#58)

<!--- Provide a general summary of your changes in the Title above -->

## Description
<!--- Describe your changes in detail -->
Adds a feature to the flashcart to determine whether RTC is supported.
This is at minimum required for correct handling of what to show on the
main menu.
It also will help with a future context menu to set the RTC time.

## Motivation and Context
<!--- What does this sample do? What problem does it solve? -->
<!--- If it fixes/closes/resolves an open issue, please link to the
issue here -->
Some flashcarts (ED64 X5, V2.5, V2.0, V1.0 & ED64P ) do not support it.

## How Has This Been Tested?
<!-- (if applicable) -->
<!--- Please describe in detail how you tested your sample/changes. -->
<!--- Include details of your testing environment, and the tests you ran
to -->
<!--- see how your change affects other areas of the code, etc. -->

## Screenshots
