[PATCH v2 15/16] bootstd: Add a command to read all files for a bootflow

[Simon Glass]

Some bootflows (such as EFI and ChromiumOS) delay reading the kernel until
it is needed to boot. This saves time when scanning and avoids needing to
allocate memory for something that may never be used.

To permit reading of these files, add a new 'bootflow read' command.

Changes in v2:
- Make the bootmeth operation optional to remove code-size impact
