[PATCH] clk: rockchip: mark aclk_emmc_noc as a critical clock on rk3399

From: Xing Zheng <zhengxing at rock-chips.com>

We don't have code to handle any of the noc clocks in rk3399 and they're
all just listed as critical clocks.  Let's do the same for
aclk_emmc_noc.

Without this clock being marked as critical we have problems around
suspend/resume after commit 20c389e656a8 ("clk: rockchip: fix incorrect
aclk_emmc source gate bits on rk3399").  Before that change we were
presumably not actually gating any of these clocks because we were
setting the wrong gate.
