HSW and BDW have SRD_AUX_{CTL, STATUS} registers that the driver needs to
setup for the HW to use whenever exiting PSR. SKL+ hardware use hardcoded
values for the same and do not need any registers to be setup. So, use
drm_dp_dpcd_writeb() for a one-time write during PSR enable and setup the
PSR aux registers on HSW and BDW for later use by HW.
We also end up writing to reserved bits in SRD_AUX_CTL by reusing
intel_dp->get_aux_send_ctl() for HSW and BDW, fix this.
Since the AUX register setup is source side programming, move the call
to enable_source() from enable_sink().

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
