Subject: [PATCH 1/2] rapidio: specify the type for tristate choice explicitly

If the type of choice is not specified, it is implied by the first
entry within the choice block.

In this case, the first (and only) entry, RAPIDIO_ENUM_BASIC, is
tristate, hence this choice behaves as tristate.

Kconfig will stop this implication because it has a bug, and 99% of
choice use cases are bool. In fact, this is the only instance of
tristate choice in the kernel.

Before transitioning the default choice type to 'bool', specify the
type explicitly for this case.
