The GRUB_DISABLE_SUBMENU option is different than the others in the sense that it has to be set to "y" instead of "true" to be enabled. That causes a lot of confusion to users, some may wrongly set it to "true" expecting that will work the same than with most options, and some may set it to "yes" since for other options the value to set is a word and not a single character. This patch changes all the grub.d scripts using the GRUB_DISABLE_SUBMENU option, so they check if it was set to "true" instead of "y", making it consistent with all the other options. But to keep backward compatibility for users that set the option to "y" in /etc/default/grub file, keep testing for this value. And also do it for "yes", since it is a common mistake made by users caused by this option being inconsistent with the others.
