ec/intel: read board ID one time from EC per stage

Using static variables to store the board ID optimizes boot time by
reading the ID once per stage and retaining it for subsequent use.
This approach reduces redundant hardware access, ensuring efficient
and consistent retrieval of the board ID throughout the boot process.
Static variables help streamline operations, minimize overhead, and
improve performance by maintaining the board ID in a fixed memory
location, enhancing the efficiency of each boot stage.
