Function imx_anatop_get_digprog() that reads register ANADIG_DIGPROG is called to identify silicon version. Users might query silicon version earlier than regmap subsystem is ready. For example, imx6q clock driver query revision in mx6q_clocks_init(), where regmap is not initialized yet. Change imx_anatop_get_digprog() to map anatop block and read ANADIG_DIGPROG in the native way, so that the function can work at very early stage. While at it, let's move imx_print_silicon_rev() back to imx6q_timer_init() to have the message show up a little earlier. Signed-off-by: NShawn Guo <shawn.guo@linaro.org>

RBC is to control whether some ANATOP sub modules can enter lpm mode when SOC is into STOP mode, if RBC is enabled and PMIC_VSTBY_REQ is set, ANATOP will have below behaviors: 1. Digital LDOs(CORE, SOC and PU) are bypassed; 2. Analog LDOs(1P1, 2P5, 3P0) are disabled; As the 2P5 is necessary for DRAM IO pre-drive in STOP mode, so we need to enable weak 2P5 in STOP mode when 2P5 LDO is disabled. For RBC settings, there are some rules as below due to hardware design: 1. All interrupts must be masked during operating RBC registers; 2. At least 2 CKIL(32K) cycles is needed after the RBC setting is changed. Signed-off-by: NAnson Huang <b20788@freescale.com> Signed-off-by: NShawn Guo <shawn.guo@linaro.org>

Anatop module have sereval configurations for user to reduce the power consumption in suspend, provide suspend/resume interface for further use and enable fet_odrive to reduce CORE LDO leakage during suspend. As we have a common anatop file, remove all the operations of anatop module in other files, use anatop interfaces to do that.
