meta-mellanox: meta-msn: add scripts to initramfs.
We using same image for both flash.
Modify obmc-init.sh for detect flash and
minimal boot from second flash.

+# Script to burn entire 32MB of BMC SPI Flash
+#
+# Usage:
+# a) Local: /run/initramfs/update_all <bmc-image-file>
+# b) Remote: sshpass -p "<root-password>" ssh root@<ip> '/run/initramfs/update_all <bmc-image-file>'
+#
+# Assumptions:
+# <bmc-image-file> is a 32MB file representing all partitions in BMC SPI Flash
+# <bmc-image-file> exists on local filesystem
+# /dev/mtd0 represents entire BMC SPI Flash device
+# /dev/mtd5 is a JFFS2 filesystem (rwfs) partition
+# /bsp/reset/bmc_upgrade is symlink pointing to proper sticky bit in CPLD
+#
