[U-Boot] [RFC][PATCH] block: Enable block cache by default

[Marek Vasut]

The recent ext4 cache discussion would indicate that the block cache
is a desired feature, yet hidden and not enabled most of the time.
Enable the block cache by default since it provides significant block
device access performance improvement and if there are some users who
cannot enable it ie. due to size limitations, those should disable it
explicitly in their board config.
