Add CONFIG_BRINGUP option to help debug signals for bringup
When this option is configured, two changes take place.
First, the AP doesn't power on by default when the EC reboots. To boot it,
you can run the "powerbtn" command, or poke the power button manually, or
any of the normal things.
Second, we watch for power-related signal changes (anything that's connected
to the power_signal_interrupt() function) and keep track of them as they
happen. After a second with no further changes, we print the time and value
of each change. For example:
[19.939212 Port 80: 0x29]
[19.967971 HC 0x23]
[19.976236 Port 80: 0x3a]
[19.995700 HC 0x87]
[20.567884 Port 80: 0x73]
11 signal changes:
19.638241 +0.000000 PCH_SLP_SUS_L => 1
19.654378 +0.016137 PCH_SLP_S5_L => 1

[21.908551 Port 80: 0xf0]
[21.908855 HC 0x48]
BUG=none
BRANCH=ToT
TEST=manual
Build with CONFIG_BRINGUP, notice those two changes.
