Alex did the reset workaround in power_on function. <https://chromium-review.googlesource.com/#/c/214360/> Now, the new version RK808 has fixed this issue, so we needn't this workaround. BUG=chrome-os-partner:35976 BRANCH=veyron TEST=The BUCK1_ON_VSEL register default value is 0x18, and coreboot and kernel will change this register to other value, but never set 0x18 to it. So we can read this register in coreboot and print out to console to check whether the RK808 reset to default after cold reboot. With this patch, the value always reset to 0x18. I have test on jerry, mighty, speedy. TEST=Use "i2cset -f -y 0 0x1b 0x21 0x0f" Power up system: it should power back up TEST=Use "i2cset -f -y 0 0x1b 0x21 0x0f" Press refresh-power: system should reboot TEST=Use "i2cset -f -y 0 0x1b 0x2a 0x00" Shut down and power back up. Use "i2cget -f -y 0 0x1b 0x2a". Confirm back to 0xff. TEST=Use "i2cset -f -y 0 0x1b 0x2a 0x00" Press refresh-power: system should reboot Use "i2cget -f -y 0 0x1b 0x2a". Confirm back to 0xff.
