MLK-9708 arm: imx: add low power idle support for i.mx6sx
Enable low power idle for i.MX6SX:
WFI -> first level idle;
WAIT mode -> second level idle;
Low power idle -> third level idle, only when system is in low bus mode.
In low powe idle mode, below operations will be done:
ARM power off;
AHB freq lower to 3MHz;
PERCLK freq lower to 6MHz;
MMDC freq lower to 1MHz;
Anatop will be put into low power mode, and regular band-gap will
be off and low power band-gap will be enabled instead.
Also, in low power idle mode, 24MHz XTAL power will be off and 24MHz clk
source will be switched to RC-OSC to save power, this feature is only
enabled on i.MX6SX TO1.2.
This patch is cherry-picked from L3.14.y, it is the latest version, below
conflicts are fixed.
