kernel/rv1106: PVTM VERIFIED — both monitors probe + read (7th driver)

Browse Source 
Whole-driver port (mainline has no rockchip pvtm): copied vendor rockchip_pvtm.c
+ pvtm.h. 6.18 deltas: thermal_zone opaque -> thermal_zone_get_temp; of_device.h.
Real blocker: vendor of_match_table wrapped rv1106 entries in #ifdef
CONFIG_CPU_RV1106 (nonexistent in mainline) -> devices+driver present but never
bound, probe silent. Dropped the guard -> both bind.

Verified: ff240000.pvtm + ff390000.pvtm probed; /sys/kernel/debug/pvtm/{core,pmu}/
value read ring-osc counts (71682 90462 / 35772). pvtm/PORT-DONE.md.
