Christophe JAILLET 3f43926f27 i3c/master/mipi-i3c-hci: Fix a potentially infinite loop in 'hci_dat_v1_get_index()'
The code in 'hci_dat_v1_get_index()' really looks like a hand coded version
of 'for_each_set_bit()', except that a +1 is missing when searching for the
next set bit.

This really looks odd and it seems that it will loop until 'dat_w0_read()'
returns the expected result.

So use 'for_each_set_bit()' instead. It is less verbose and should be more
correct.
