Switch odroid to use distro_bootcmd.

Using distro_bootcmd standardizes board behavior across many platforms. This is particularly useful for distributions supporting multiple boards without requiring custom configuration for each board.

There are a few changes needed to support distro_bootcmd, such as fixing the default value for the console setting, increasing the environment size, and allowing distro bootcmd to set the default bootdelay.

These patches have been used in Debian's u-boot packaging since May of 2016.

Vagrant Cascadian (4):
Fix default console on odroid to only specify the device, as
"console=" is redundant with the boot environment.
Increase the default environment size on odroid, as
config_distro_bootcmd requires a more space for the environment.
Switch odroid to use config_distro_bootcmd.
Inherit default value for bootdelay from distro_bootcmd on odroid.

The default value with distro_bootcmd is 2 seconds, which is reasonably fast, and provides a consistent experience across platforms supporting distro_bootcmd.

The current bootdelay value of 0 seconds is a bit challenging to interrupt when desired.

Hi Vagrant,
