Kconfig: Migrate BOUNCE_BUFFER
The bounce buffer is used by a few drivers (most of the MMC drivers)
to overcome limitations in their respective DMA implementation.
This moves the configuration to Kconfig and makes it user-selectable
(even though it will be a required feature to make those drivers
work): the expected usage is for drivers depending on this to 'select'
it unconditionally from their respective Kconfig (see follow-up
patches).
This commit includes a full migration using moveconfig.py to ensure
that each commit compiles. To ensure bisectability we update
dependencies of various drivers to now select BOUNCE_BUFFER when needed.
[trini: Squash all patches to ensure bisectability]
