Change user configurable booting init

WindCharger booting sequence will be:
1. kernel start $(init) from kernel cmdline
2. $(init) start inits and trigger sysv init @ /sbin/init
3. sysv init take over

The original init script in uboot is /sbin/init, change it
to /init. /sbin/init is used for sysv init.
