ARM: mach-realview and mach-versatile: retire custom LED code
This replaces the custom LED trigger code in mach-realview with some overarching platform code for the plat-versatile family that will lock down LEDs 2 thru 5 for CPU activity indication. The day we have 8 core ARM systems the plat-versatile code will have to become more elaborate. Tested on RealView PB11MPCore by invoking four different CPU hogs (yes > /dev/null&) and see the LEDs go on one at a time. They all go off as the hogs are killed. Tested on the PB1176 as well - just one activity led (led 2) goes on and off with CPU activity. (bryan.wu@canonical.com: use ledtrig-cpu instead of ledtrig-arm-cpu) Cc: Richard Purdie <rpurdie@rpsys.net> Signed-off-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Bryan Wu <bryan.wu@canonical.com> Acked-by: Pawel Moll <pawel.moll@arm.com>
