soc/rockchip/rk3288: Add fall through comment
Judging from the state machine on page 281 of the Rockchip RK3288
Technical Reference Manual (Rev 1.0 - Jun 2015), the fall through
from the INIT_MEM -> CONF states is intentional, since that is the
only way to get to the ACCESS state. Add a comment to explain this.
