[PATCH 2/2] commands: remove old Y-Modem implementation

[Robert Jarzmik <robert.jarzmik@free.fr>]

From: Robert Jarzmik <robert.jarzmik@intel.com>

As a new implementation of Y-Modem protocol is available,
switch from old implementation to the new one :
 - remove old xyzModem* files
 - remove old command loady2
 - rename command loady2 to loady

Signed-off-by: Robert Jarzmik <robert.jarzmik@intel.com>
