[PATCH 2/3] kconfig: remove support for "bool" prompt for choice entries

[Masahiro Yamada <masahiroy@kernel.org>]

Since commit fde192511bdb ("kconfig: remove tristate choice support"),
all choice blocks are now boolean. There is no longer a need to specify
the choice type explicitly.

All "bool" prompts in choice entries have been converted to "prompt".

This commit removes support for the "bool" syntax in choice entries.
