softirq shouldn't be bounded to vcpu thread. One issue for this
is shell (based on timer) can't work if we don't start any guest.
This change also is trying best to make softirq handler running
with irq enabled.
Also update the irq disable/enabel in vmexit handler to align
with the usage in vcpu_thread.

- add missing brackets for 'if/else' statements based on MISRA-C
requirements
v1 -> v2:
* add brackets for each conditions in 'if' statements to improve
the readability
* modify 'ptdev_init' to make the logic clearer

1. add register_softirq to register a softirq handler
2. rename exec_softirq to do_softirq; raise_softirq to fire_softirq.
3. in do_softirq call registered softirq handler not call
the device softirq handle function directly
4. enable irq after vm exit and disable irq after the first
call do_softirq before vm enter.
5. call do_softirq again when irq disabled to handle the risk
unhandled softirq.
6. rename SOFTIRQ_DEV_ASSIGN to SOFTIRQ_PTDEV
7. remove SOFTIRQ_ATOMIC
