linux: Disable lock-step for all iot2050 boards

The PG1 A variant of the iot2050 series has been identified which partially lacks support for lock-step mode. This implies that all iot2050 boards can't support this mode. As a result, lock-step mode has been disabled across all iot2050 boards for consistency and to avoid potential issues. Signed-off-by: Li Hua Qian <[email protected]>
