i2c: boardinfo: Annotate code used in init phase only
Annotate two places in boardinfo code:
- __i2c_first_dynamic_bus_num is set in init phase. Annotate it as
__ro_after_init to prevent later changes.
- i2c_register_board_info() is used in init phase only, so annotate it
as __init, allowing to free the memory after init phase.
This is safe, see comment: "done in board-specific init code near
arch_initcall() time"
