msm: dma: Update the clk gating timeout to 100msec from 1sec.

As part of LPAII, the power profiling showed that having 100msec timeout
is letting the AXI switch to low frequency as soon as the APROC collapses.
Having this timeout as 1 sec is pushing the AXI to stay high for longer
time hence causing more power drain. Hence with this change this time
out is updated to 100msec.
