driver core: platform: Declare early_platform_cleanup() prototype

[ Upstream commit 1768289b44bae847612751d418fc5c5e680b5e5c ]

Compiler is not happy:

  CC      drivers/base/platform.o
drivers/base/platform.c:1557:20: warning: no previous prototype for ‘early_platform_cleanup’ [-Wmissing-prototypes]
 1557 | void __weak __init early_platform_cleanup(void) { }
      |                    ^~~~~~~~~~~~~~~~~~~~~~

Declare early_platform_cleanup() prototype in the header to make everyone happy.
