This cleanup series gets rid of <mach/timex.h> for platforms not using 

ARCH_MULTIPLATFORM. (For multi-platform code it's already unused since
 387798b (ARM: initial multiplatform support).)
 
 To make this work some code out of arch/arm needed to be adapted. The
 respective changes got acks by their maintainers to be taken via armsoc
 (with Andrew Morton substituting for Alessandro Zummo as rtc maintainer).
 
 Compared to the previous pull request there was another patch added that
 fixes a (non-critical) regression on ixp4xx. Olof Johansson asked to not
 squash this fix into the original commit to save him from the need to
 reverify the series.

Optional properties:
- atmel,use-dma-rx: use of PDC or DMA for receiving data
- atmel,use-dma-tx: use of PDC or DMA for transmitting data
- rts-gpios: specify a GPIO for RTS line. It will use specified PIO instead of the peripheral
function pin for the USART RTS feature. If unsure, don't specify this property.
- add dma bindings for dma transfer:
- dmas: DMA specifier, consisting of a phandle to DMA controller node,
memory peripheral interface and USART DMA channel ID, FIFO configuration.
