[U-Boot] [PATCHv3 0/6] dm: cache: add dm cache driver

[Dinh Nguyen]

Hi,

This is V3 of the series to add a UCLASS_CACHE dm driver to handling
the configuration of cache settings. Place this new driver under
/drivers/cache. In this initial revision, the driver is only configuring
what I think are essential cache settings. The more comprehensive cache
settings can be done in the OS.

Diffs from v2:
- Add cache_get_info() to check for non-zero value
- Add comments to cache_info struct
- Fix up nits from Simon Glass
