Revert "misc: add Tizen reboot notifier for passing reboot parameter"

Tizen specific inform-reboot kernel module has been moved to
linux-tizen-modules-source repository, so keeping a copy of it
in each kernel repository is not needed anymore.

This reverts commit 04598d754f6adbc90f1852c6e09ddfc3b3834f2c.

-         This enables support for passing reboot parameter through inform
-         partition. It is required to determine booting mode (e.g., fota or
-         normal). After passing reboot parameter, u-boot checks the contents
-         of inform file and then determines proper booting mode.
