hwmon: (asus-ec-sensors) add ROG STRIX X670E-A GAMING WIFI

Browse Source 
The ROG STRIX X670E-A GAMING WIFI is missing from the driver's DMI
table. Consequently, the board lookup fails with -ENODEV,
asus_ec_sensors does not load, and no asusec hwmon device or EC
temperature readings are available.

The board uses the same EC sensors, access mutex, and AMD 600-series
register layout as the ROG STRIX X670E-E GAMING WIFI. Add its DMI entry
using the existing X670E-E board information and document the board as
supported.

Before the change, there was no asusec device under /sys/class/hwmon and
there were no EC readings. After the change, the driver registered four
sensors with representative readings of 57-61 C for CPU, 68-71 C for
CPU package, 43-44 C for motherboard, and 49-52 C for VRM.

The readings correlated with nct6775 and k10temp. Repeated polling with
both hwmon drivers loaded produced no EC access, bank-switch, concurrent
access, or locking errors.

Tested on an ASUS ROG STRIX X670E-A GAMING WIFI with BIOS 2704.
