svn commit: r327418 - head/sys/powerpc/ps3

[Nathan Whitehorn]

Author: nwhitehorn
Date: Sun Dec 31 06:10:07 2017
New Revision: 327418
URL: https://svnweb.freebsd.org/changeset/base/327418

Log:
  Use data from the boot loader to pick the appropriate output graphics mode
  instead of hard-coding a default. This information is passed implicitly by
  the PS3 firmware and can be relied upon. Also adjust the default mode, if
  somehow firmware doesn't pass one, to 1920x1080 from 720x480 since it is
  2017.
