and how would you know before hand if it's going to be used or not ?

The thing is that what you are proposing will not scale when we have too
many boards with different transceivers. Then we will end up with things
like:

config USB_ARCH_HAS_OHCI
	boolean
	# ARM:
	default y if SA1111
	default y if ARCH_OMAP
	default y if ARCH_LH7A404
	default y if ARCH_S3C2410
	default y if PXA27x
	default y if PXA3xx
	default y if ARCH_EP93XX
	default y if ARCH_AT91
	default y if ARCH_PNX4008 && I2C
	default y if MFD_TC6393XB
	default y if ARCH_W90X900
	default y if ARCH_DAVINCI_DA8XX
	# PPC:
	default y if STB03xxx
	default y if PPC_MPC52xx
	# MIPS:
	default y if MIPS_ALCHEMY
	default y if MACH_JZ4740
	# SH:
	default y if CPU_SUBTYPE_SH7720
	default y if CPU_SUBTYPE_SH7721
	default y if CPU_SUBTYPE_SH7763
	default y if CPU_SUBTYPE_SH7786
	# more:
	default PCI

which to me would be much better that e.g. SA1111 does a select
USB_ARCH_HAS_OHCI like it's done for HAVE_CLK
