/*
 * Mediatek m4u generation 1 such as mt2701 has flat m4u port numbers,
 * the first port's id for larb[N] would be the last port's id of larb[N - 1]
 * plus one while larb[0]'s first port number is 0. The definition of
 * MT2701_M4U_ID_LARBx is following HW register spec.
 * But m4u generation 2 like mt8173 have different port number, it use fixed
 * offset for each larb, the first port's id for larb[N] would be (N * 32).
