rockchip/rk3399: extend delay between saradc power up and start command
We found when ambient temperature low, with now saradc frequency and delay between saradc power up and start command, there may get wrong adc value, then get the wrong ramid or boardid, so lower the saradc frequency and add the delay time between power up and start command. BUG=b:70692504 BRANCH=gru TEST=test on Dru in 0C temperature, always get right adc value Change-Id: I42e49ca63299479912fa05e2a62cba6f2de4b337 Signed-off-by: Lin Huang <hl@rock-chips.com> Reviewed-on: https://review.coreboot.org/23515 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Julius Werner <jwerner@chromium.org> Reviewed-by: Paul Menzel <paulepanter@users.sourceforge.net>
