...
We want them weak in case any of this can leak back in the 5V
domain.

gateware/sysmgr: Make sure sys_start _always_ forces system clock ON
...
Before it was only sensitive to rising edge. But for the "start" we
actually want to force it on if active to avoid race condition in the
software where:
- CPU clears the condition of the wakeup
- New wake up event happens right after it
- CPU asks for shutdown
- And then no rising edge happens because wakeup is already high
For shutdown it's good that it's rising edge dependent since the
OFF command signal _might_ stay high if the system clock shuts down

gateware/firmware: Add better support for buttons
...
The press events are detected in the gateware and latched
and the firmware can just read them as "events". They also
trigger sys clock domain wake up if it was sleeping.
This is better since the 'sys' clock domain can be shutdown for
some non-negligible amount of time and it could lead to missed
presses or latency.
