MLK-11204 ARM: imx: set int_mem_clk_lpm bit bit when entering wait mode on 6ul

This bit is used to keep the ARM Platform memory clocks enabled if
an interrupt is pending when entering low power mode. This bit should
always bet set when the CCM_CLPCR_LPM bits are set to 01(WAIT Mode) or
10 (STOP mode) without power gating.
