Why is this change needed if you do not have a dependency on the new irq_steer driver?

Why is this change needed if you do not have a dependency on the new irq_steer driver?
This is a irqsteer driver(CONFIG_MCUX_COMPONENT_driver.irqsteer_1) in mcux sdk. It needs to be enabled by default.
The i2c driver(drivers/i2c/i2c_mcux_lpi2c.c) of zephyr will use lpi2c driver(drivers/lpi2c/fsl_lpi2c.c) of mcux sdk,
the lpi2c driver of mcux sdk will can api EnableIRQ(drivers/common/fsl_common_arm.h) of mcux sdk,
EnableIRQ -> IRQSTEER_EnableInterrupt
