pcie_regs: drop duplicated indicator value macros 

We already have indicator values in
include/standard-headers/linux/pci_regs.h , no reason to reinvent them
in include/hw/pci/pcie_regs.h. (and we already have usage of
PCI_EXP_SLTCTL_PWR_IND_BLINK and PCI_EXP_SLTCTL_PWR_IND_OFF in
hw/pci/pcie.c, so let's be consistent)
