rp2/cyw43_configport: Make sure only core0 executes a __WFI().

Browse Source 
This commit executes __WFI() on core 0 only to avoid core1 locking up since
it doesn't enable any interrupts by default (except for `SIO_IRQ_PROC1`).
This fixes a lockup when calling `cyw43_do_ioctl` from core1.

Fixes issue #9597.
