[PATCH 2/6] kdump: Modify kdump script to start the firmware assisted dump.

During service kdump start, if firmware assisted dump is not enabled then fallback to starting of existing kexec based kdump. If firmware assisted is enabled but not running, then start firmware assisted dump by echo'ing 1 to '/sys/kernel/fadump_registered' file.
