MLK-12375 ARM: imx: improve ARM power up time for i.MX6UL TO1.1
On i.MX6UL, PGC_CPU_PUPSCR_SW's counter uses IPG/2048 as clock
source, as IPG is at 1.5MHz during low power idle, so the power
up time can be up to 1.3mS which is too long for idle.
Since TO1.1, design team re-define the bit[5], if this bit is
set to 1, the clock will be IPG/32, ~22us, enable this function
for TO1.1, the latency value for low power idle needs to be
adjusted accordingly.
