Bug description:
CONFIG_SMP=y
Suppose we have 2 cores in SMP, here is the ps return:
PID GROUP CPU PRI POLICY TYPE NPX STATE STACK USED FILLED COMMAND
0 0 0 0 FIFO Kthread N-- Assigned 004076 000748 18.3% CPU0 IDLE
1 0 1 0 FIFO Kthread N-- Running 004096 000540 13.1% CPU1 IDLE
nsh> kill -4 0
or:
nsh> kill -4 1
system blocked.
Reason:
In func xx_sigdeliver() restore stage, when saved_irqcount == 0, that means
rtcb NOT in critical_section before switch to xx_sigdeliver(), then we need
reset the critical_section state before swith back.
Fix:
Add condition to cover saved_irqcount == 0.

This commits adds support for the ESP32-C3 IO Mux and GPIO Matrix. It
also includes necessary board logic to run the GPIO example with 2
outputs.

Summary:
- This commit changes spinlock APIs (spin_lock_irqsave/spin_unlock_irqrestore)
- In the previous implementation, the global spinlock (i.e. g_irq_spin) was used.
- This commit allows to use caller specific spinlock but also supports to use
g_irq_spin for backword compatibility (In this case, NULL must be specified)
Impact:
- None
Testing:
- Tested with the following configurations
- spresnse:wifi, spresense:wifi_smp
- esp32-devkitc:smp (QEMU), sabre6-quad:smp (QEMU)
- maxi-bit:smp (QEMU), sim:smp
- stm32f4discovery:wifi

Don't declare riscv_addregion if CONFIG_MM_REGIONS is < 1, so we won't
have to provide a dummy stub for every chip.
Also rename the function from up_addregion to riscv_addregion since it's
not exported outside the arch directory.
