It might be better to move the config out of mach-msm into
arch/arm/Kconfig.debug. I think the eventual goal is to remove all these
#defines for the physical/virtual address and have users enter the
addresses in Kconfig similar to how Russell has done for the pl01X. If
that happens then we end up with a DEBUG_MSM_UART (for 7201,8x50, 7x30)
and DEBUG_QCOM_UARTDM for all others and the help text would indicate
which addresses to use.
