Mark switch cases where we are expecting to fall through.

This patch fixes the following warning (Building: bcm63xx_defconfig mips):

arch/mips/pci/ops-bcm63xx.c: In function ‘bcm63xx_pcie_can_access’:
arch/mips/pci/ops-bcm63xx.c:474:6: warning: this statement may fall through [-Wimplicit-fallthrough=]
   if (PCI_SLOT(devfn) == 0)
      ^
arch/mips/pci/ops-bcm63xx.c:477:2: note: here
  default:
  ^~~~~~~
