DRA7/AM57xx devices can be operated in many different configurations.
When the SoC is supposed to support a configuration where low power mode
state may involve the SoC completely powered off and DDR is in self
refresh, SoC EMIF controller should not be the master of the reset
signal and an external entity might be in control of things.

The default configuration of Linux on TI evms involve not powering off
the voltage rails (due to various reasons including reliability concerns)
and must not allow DDR reset to be controlled by EMIF. On platforms
where external entity might control the reset signal, this configuration
will be a "dont care".

This introduces the part start and part size sub-commands. The purpose of these
is to store the start block and size of a partition in a variable, given the
device and partition number.

This allows reading raw data that fits a single partition more easily.
For instance, this could be used to figure out the start block and size of a
kernel partition when a partition table is present, given the partition number.

This allows using only one of either raw or fs mode for SPL mmc boot, without
the need to have provisions for the other. In particular, a device may have
U-Boot installed on a file system on the mmc, without ever needing to read
U-Boot from raw memory. Thus, there is no reason to provide a sector or
partition for raw mode. This allows this behaviour and still provides a robust
fallback mechanism in case provisions for both modes are defined.
