Use subdir-ccflags-* instead of ccflags-* to inherit the debug settings from Kconfig when traversing subdirectories.

commit e8e9aababe60 ("PCI: Apply CONFIG_PCI_DEBUG to entire drivers/pci hierarchy") Author: Junhao He hejunhao2@hisilicon.com Date: Thu Feb 4 19:30:15 2021 +0800
PCI: Apply CONFIG_PCI_DEBUG to entire drivers/pci hierarchy
CONFIG_PCI_DEBUG=y adds -DDEBUG to CFLAGS, which enables things like pr_debug() and dev_dbg() (and hence pci_dbg()). Previously we added -DDEBUG for files in drivers/pci/, but not files in subdirectories of drivers/pci/.
Add -DDEBUG to CFLAGS for all files below drivers/pci/ so CONFIG_PCI_DEBUG applies to the entire hierarchy.
