remoteproc/omap: set bootaddr support
Some remote processors (like OMAP4's DSP) require we explicitly
set a boot address from which they'd start executing code when
taken out of reset.
Support for this is now being added to the omap-specific remoteproc
driver through a set_bootaddr function in the platform data which,
if needed, must be set according to the backend remote processor.
For OMAP4's dsp we can use the following control function:
.set_bootaddr = omap_ctrl_write_dsp_boot_addr
