arch/arm/Kconfig: minor tweaks
MMC: add mmc_blk_disable_wr_packing to block.c

This fixes an undefined reference.
mach-msm/Kconfig: remove HAVE_ARM_ARCH_TIMER

This prevents timer.o from being compiled by our Makefile and causes
undefined references.
mach-msm/include/mach/dma.h: Add MSM8960 stuff

Devices-8960/8064 needs these definitions.
timer.c: uncomment timer.h
mach-msm: remove unneeded file
