Subject: [PATCH v4 04/21] hwmon: (mr75203) update pvt->v_num and vm_num to the actual number of used sensors

This issue is relevant when "intel,vm-map" is set in device-tree, and
defines a lower number of VMs than actually supported.

This change is needed for all places that use pvt->v_num or vm_num
later on in the code.

Fixes: 9d823351a337 ("hwmon: Add hardware monitoring driver for Moortec MR75203 PVT controller")
Signed-off-by: Eliav Farber <farbere@...zon.com>

V4 -> v3:
- Update also vm_num to actual number of VMs.
