From: Peng Fan <peng....@nxp.com>
With partition reset supported for i.MX8QM/QXP/95 and etc, when linux
mmc runtime suspended, the mmc clks are gated off. While at same time
system controller reset Cortex-A cores because of various reasons(
WDOG timeout and etc), with SPL run again, only enable PER clk is not
enough, also need to enable AHB/IPG clk, here use clk bulk API to enable
all the clocks.

V2:
Update commit log and use clk bulk API per Fabio.
