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.

mmc: jz_mmc: Compile-out write support if disabled

Do not build write support, unless it's enabled.

In the SPL case, this change will typically remove
precious bytes (as write support is most often
not needed in SPL).

This is important on this platform, where the maximum
SPL size is 14 KiB.

With gcc v7.3, this change saves 144 bytes producing:

size spl/u-boot-spl
   text    data     bss     dec     hex filename
   9240     752     712   10704    29d0 spl/u-boot-spl

To make the code easier to compile-out and more
readable, a pair of read_data/write_data helpers are created.
