PATCH 1/1 csky: Remove compile warning for CONFIG_SMP

From: "Guo Ren (Alibaba DAMO Academy)" <[email protected]>

When CONFIG_SMP is enabled, there is a compile warning:

arch/csky/kernel/smp.c:242:6: warning: no previous prototype for 'csky_start_secondary' [-Wmissing-prototypes]
242 | void csky_start_secondary(void)

      |      ^~~~~~~~~~~~~~~~~~~~

Add a similar prototype with csky_start in sections.h.
