Like done for when __var_args__ were used, but size-wise it's also
benefitial to avoid _PICK() used for 3 ports/pipes:

	$ size build64/drivers/gpu/drm/i915/i915.o{.old,.new}
	   text    data     bss     dec     hex filename
	4026288  185703    6984 4218975  40605f build64/drivers/gpu/drm/i915/i915.o.old
	4025496  185703    6984 4218183  405d47 build64/drivers/gpu/drm/i915/i915.o.new
