i2c: imx: use guard to take spinlock

Browse source

Use guard to automatically release the lock after going out of scope
instead of calling it manually.

i2c_imx_slave_handle() can safely be entered with the lock held.

Refactored the i2c_imx_isr function so that i2c_imx_master_isr
does not participate in the guard scope

So Using scoped_guard simplifies the control flow
by ensuring consistent and automatic unlock,
which improves readability without affecting correctness.
