[PATCH v2] staging: gdm724x: make DEVICE_STRING array const

[pdsj2807@gmail.com]

From: Palak Raval <pdsj2807@gmail.com>

The DEVICE_STRING array contains pointers to string literals and is
never modified.

Declare it as 'const char * const' to improve const correctness and
prevent accidental modification.

v2:
- Drop unrelated formatting changes
- Keep only the DEVICE_STRING const-correctness change
