[PATCH] memory: mtk-smi: Use ARRAY_SIZE to define MTK_SMI_CLK_NR_MAX

[AngeloGioacchino Del Regno]

This definition is tied to the number of SMI common clocks (the array
mtk_smi_common_clks): improve the definition by using the ARRAY_SIZE
macro instead. That will also reduce room for mistakes when updating
the aforementioned array in the future.

Thanks for the patch. I sent mtk-smi pull request some time ago and it
is late in the cycle, so this might need to wait for next cycle. I'll
keep it in my queue.

Best regards,
Krzysztof
