Subject: [PATCH] ARM: Add method to mach/pci.h

Adding method pcibios_report_status() to mach/pci.h, so as to remove the
extern declaration in dc21285.c, and remove missing-prototypes warning
in kernel/bios32.c.

../arch/arm/kernel/bios32.c:59:6: warning: no previous prototype for ‘pcibios_report_status’ [-Wmissing-prototypes]
 void pcibios_report_status(u_int status_mask, int warn)
      ^~~~~~~~~~~~~~~~~~~~~
