Add p1 gen 3

[libussa]

hello,
I have a p1 gen 3, dual fans. Can you add it? I can provide info but I don;t know where to look for the prefix

Prefix should be N2V - source: https://download.lenovo.com/pccbbs/mobiles/n2vuj09w.txt
So you can add line
TPACPI_Q_LNV3('N', '2', 'V', TPACPI_FAN_2FAN_CONTROL), /* P1/X1 Extreme (3rd gen) */
to the
static const struct tpacpi_quirk fan_quirk_table[] __initconst
table.

But this model is already supported in the official linux kernel since 5.10 kernel version (*).
https://github.com/torvalds/linux/blob/v5.10/drivers/platform/x86/thinkpad_acpi.c#L8787
so you can just use current kernel.

(*) however that (official linux kernel) version doesn't support setting different speed for left and right fan, both are running at the same speed
