ARM: Optionally allow ARMv6 to use 'normal, bufferable' memory for DMA
Provide a configuration option to allow the ARMv6 to use normal
bufferable memory for coherent DMA. This option is forced to 'y'
for ARMv7, and offered as a configuration option on ARMv6.
Enabling this option requires drivers to have the necessary barriers
to ensure that data in DMA coherent memory is visible prior to the
DMA operation commencing.
