[ot] hw/misc: pulp_rv_dm: Reset idle cache bitmask

AlexJones0 · AlexJones0 · commit 1247809f60fe · 2025-11-27T13:28:40.000Z
Reset the `idle_bm` on a reset of the Pulp RV_DM, as a system / NDM
reset while a hart is halted can cause the hart to resume, whilst the
Pulp RV_DM still thinks the hart is halted (thus it never acknowledges
the halted state, and it never appears in the DM's `dmstatus`).
