[PATCH] platform/x86: thinkpad_acpi: Fix fan speed reporting on Edge E330

[Andrew Onyshchuk <andryk.rv@gmail.com>]

The ThinkPad Edge E330 with H3 firmware uses the non-standard EC fan
register block. Without a matching quirk, thinkpad_acpi reads the legacy
tachometer registers and reports 0 RPM.

Add the H3 BIOS family to TPACPI_FAN_NS so the driver reads the fan
period from EC register 0x95 using the existing non-standard reporting
path.

Tested on a ThinkPad Edge E330 with BIOS H3ET77WW and EC H3EC35WW.
