i3c: mipi-i3c-hci: Fix missing STAT_IBI_STATUS_THLD in PIO mode

Browse source

In PIO mode initialization, STAT_IBI_STATUS_THLD was missing from
pio->enabled_irqs. As a result, the host controller interrupt signal for
IBI threshold was never enabled when transfer starts, preventing IBI
status descriptors from being properly processed in PIO mode.

Include STAT_IBI_STATUS_THLD in pio->enabled_irqs so that the IBI
threshold interrupt is activated alongside error interrupts upon the first
transfer.
