ARM: imx6q: add the missing esai_ahb clock
The esai_ahb clock is derived from ahb and used to provide ESAI the capability of register accessing and FSYS clock source for I2S clocks dividing. The gate bits of this esai_ahb clock are shared with the esai clock -- the baud clock, so we need to call imx_clk_gate2_shared() for these two clocks.
