dmaengine: imx-sdma: utilize compiler to calculate ADDRS_ARRAY_SIZE_V<n>

The macros SDMA_SCRIPT_ADDRS_ARRAY_SIZE_V<n> actually related with the
struct sdma_script_start_addrs.

struct sdma_script_start_addrs {
        ...
	/* End of v1 array */
        ...
	/* End of v2 array */
	...
        /* End of v3 array */
	...
        /* End of v4 array */
};

When add new field of sdma_script_start_addrs, it is easy to miss update
SDMA_SCRIPT_ADDRS_ARRAY_SIZE_V<n>.

Employ offsetof for SDMA_SCRIPT_ADDRS_ARRAY_SIZE_V<n> macros instead of
hardcoding numbers. the preprocessing stage will calculate the size for
each version automatically.
