Be more consistent with Kconfig language

The language used in Kconfig prompts is inconsistent. This presents application developers a messy and potentially confusing user interface (when the variation in language actually intends to communicate a variation).

Examples of phrasing used to communicate that a driver should be enabled in "Device Drivers":

Device Drivers:
  <driver>
  <driver> driver
  <driver> drivers
  <driver> Drivers
  <driver> drivers options
  <driver> support
  <driver> Support
  <driver> Configuration
  <driver> Device Drivers
  Enable <driver> driver
  add support for <driver> Drivers

Definition of Done:

• Port the Kconfig language used to be more consistent.
• Develop guidelines that can be used in code-review (and during porting) to enforce consistency.
