i3c: mipi-i3c-hci: Allow only relevant INTR_STATUS bit updates
Since MIPI I3C HCI specification version v0.8 INTR_STATUS bits 9:0 are
reserved. Version v0.5 has bits 9 and 5:0 in use but not handled by the
current driver code and not needed in DMA transfers.
PIO transfers with v0.5 would require changes to both
core.c: i3c_hci_irq_handler() and pio.c: hci_pio_irq_handler() though.
For these reasons don't enable signal updates from INTR_STATUS bits 9:0.
It allow to get rid of "unexpected INTR_STATUS" error messages on old
v0.5 IP version and is a no-op for later versions starting from v0.8.
