this patch sets memory range for IPC stuff according to register layout.
there is no memory overlap for all components.
it also sets the right hwspinlock for these components.

Add hwspinlock support for the CSR atlas7 SoC.
The Hardware Spinlock device on atlas7 provides hardware assistance
for synchronization between the multiple processors in the system
(dual Cortex-A7, CAN bus Cortex-M3 and audio DSP).

this patch adds dt-binding document for pwm-sirf. here the controller clock
can't generate PWM signals, so we need seperate clock as signal source.

move to support of_dma_request_slave_channel() and dma_request_slave_channel.
we add a xlate() to let dma clients be able to find right dma_chan by generic
"dmas" properties in dts.
