kernel: ksysfs: initialize kernel_kobj earlier
Software nodes depend on kernel_kobj which is initialized pretty late
into the boot process - as a core_initcall(). Ahead of moving the
software node initialization to driver_init() we must first make
kernel_kobj available before it.
Make ksysfs_init() visible in a new header - ksysfs.h - and call it in
do_basic_setup() right before driver_init().
