[PATCH v1] staging: vme_user: replace (1 << n) with BIT(n)

[Dharanitharan R]

In drivers/staging/vme_user/vme.c, the functions vme_register_bridge()
and vme_unregister_bridge() use bit shifts like (1 << i) and
(1 << bridge->num) to manipulate vme_bus_numbers.

Replace these shifts with the BIT(n) macro for readability,
consistency, and kernel coding style.

Changes:
- vme_register_bridge(): (1 << i) → BIT(i)
- vme_unregister_bridge(): (1 << bridge->num) → BIT(bridge->num)
