block: implement block_read/block_write functions
...
Some drivers use blk->ops->read/write. This bypasses the caching block
layer and was never intended like this. The upper API to the block layer
is the cdev layer. This patch adds block_read and block_write functions
and uses them where appropriate.

...
The FSF address has changed in the past. Instead of updating it
each time the address changes, just drop it completely treewide.

It does not necessarily means a bug when block_get fails here,
this can also be a failure on the underlying device.

block: reimplement caching
...
The current caching layer only has a single buffer for
writing and reading. The FAT driver often accesses the
fat and then data again, which currently can't be cached.
Reimplement this with a list of cached chunks. The number
of chunks and their sizes are currently hardcoded, but
that could be easily made configurable.

add block support

This adds a simple block layer to barebox. Reading and writing
to block devices can be painfully slow without caching, so
add a simple caching layer here.
