Input: synaptics - add LEN2058 to SMBus passlist for ThinkPad E490
The Lenovo ThinkPad E490 (PNP ID: LEN2058) has a Synaptics TM3471-020
touchpad that supports SMBus/RMI4 mode but is not listed in
smbus_pnp_ids[]. Without this entry, RMI4 over SMBus is not enabled
by default, and the touchpad falls back to PS/2 mode.
Adding LEN2058 to the passlist enables automatic RMI4 detection without
requiring the psmouse.synaptics_intertouch parameter, and matches
the behavior of similar ThinkPad models already in the list
(E480/LEN2054, E580/LEN2055).
Tested on ThinkPad E490 with kernel 7.0.5-zen1 and Arch Linux.
RMI4 over SMBus is confirmed working without any kernel parameters.
