ARM: davinci: da8xx: add remoteproc support

Browse Source 
Add remoteproc platform device for controlling the DSP
on da8xx. The patch uses CMA-based reservation of physical
memory block for DSP use. A new kernel command-line parameter
has been added to allow boot-time specification of the physical
memory block.
