[PATCH] video: fbdev: via: refactor deprecated strcpy

[Ajith P V <ajithpv.linux@gmail.com>]

Replace the deprecated and unbounded strcpy() function with the safer
strscpy() alternative when setting up the framebuffer fixed screen
information [1][2].

The destination buffer `fix->id` is a fixed-size character array of
16 bytes. The source `viafb_name` is currently a static global string
literal ("Via"), which safely fits the destination and poses no active
overflow risk.

However, replacing strcpy() with strscpy() aligns this driver with
the ongoing kernel-wide security initiative to eliminate unbounded
string copies, hardening the code against future modifications.

This is a proactive API cleanup and there is no functional
performance or truncation risk since `viafb_name` safely fits inside
the 16-byte struct constraints.
