ARM: msm: Drop useless teq from DEBUG_LL support
This teq was first introduced inbcc0f6a
([ARM] msm: clean up iomap and devices, 2008-09-10). It seems that DEBUG_LL support on MSM at the time had to remove the virtual mapping for the uart base. Thus when the MMU was enabled the addruart macro returned 0 and the senduart macro would test for 0 and do nothing. It was a simple way to turn off DEBUG_LL when the MMU was enabled. The virtual mapping was added back in6339f66
(msm: make debugging UART (for DEBUG_LL) configurable, 2009-11-02) but the patch forgot to remove the teq here. So as it stands the teq has been useless for two years and DEBUG_LL works fine without it.
