Add more revision support for the new i.MX6DQ tape-out (TO1.5). This
TO1.5 is the Rev 1.3 as documented in i.MX6DQ data sheet, because TO1.3
and TO1.4 are never revealed.

Add imx6sl support into imx_init_revision_from_anatop(), so that it can
be used to initialize cpu type and revision on imx6sl.

The patch creates a common function imx_init_revision_from_anatop() by
merging imx6q_init_revision() and imx_anatop_get_digprog(), so that any
SoC that encodes revision info in anatop can use it to initialize
revision.

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.

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.

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.
