i3c: master: Export i3c_master_enec_disec_locked()
The existing i3c_master_enec_locked() wrapper always treats a NACKed
ENEC CCC as a failure (M2 error). However, broadcasting ENEC to enable
Hot-Join is legitimately useful even when no I3C devices are currently
present on the bus, in which case the broadcast will be NACKed and
should not be reported as an error.
The underlying helper i3c_master_enec_disec_locked() already accepts a
suppress_m2 flag that lets callers ignore such NACKs. Expose it so that
a subsequent patch enabling Hot-Join events can issue ENEC with M2
suppression.
