Subject: [PATCH] PCI: pciehp: Cleanup unused HP_SUPR_RM macro

We do not use PCIE hotplug surprise (PCI_EXP_SLTCAP_HPS) bit anymore.
Consequently HP_SUPR_RM() macro is not used in the kernel source anymore.
Let's clean it up.

BTW, there seem to be other macros like EMI() that is not used anymore
so maybe worth removing them as well.
