ARM: s3c: fix s3c64xx_set_timer_source prototype

The prototype does not match the definition, as gcc-13 points
out:

arch/arm/mach-s3c/s3c64xx.c:169:13: error: conflicting types for 's3c64xx_set_timer_source' due to enum/integer mismatch; have 'void(unsigned int,  unsigned int)' [-Werror=enum-int-mismatch]
  169 | void __init s3c64xx_set_timer_source(unsigned int event, unsigned int source)
      |             ^~~~~~~~~~~~~~~~~~~~~~~~
