After MX6ULL DCP issue is fixed in commit 7a1cc1f, it introduces a new issue,
MX6SL will meet issue as no dcp clock is defined when initializing:
[ 3.061344] mxs-dcp 20fc000.dcp: can't identify DCP clk: -2
On mx6sl, dcp clock is always on, so the patch use dummy as dcp clock directly.

SRTC needs to be kept enabled during system poweroff,
SNVS_LP control register bit 0 SRTC_ENV must be set
to enable RTC, for software poweroff, kernel just
read the register offset and value from dtb and write
to SNVS_LP control register to poweroff system, need
to make sure bit 0 SRTC_ENV is set to enable RTC during
system poweroff.
Previous setting did NOT enable it which will cause
RTC stop running if using software poweroff.

ENGR00292341 imx6sl hwrng
Add hwrng support for i.MX6SL.
1. Add RNG driver. This driver originated as fsl-rngc.c. It
has been modified to support device tree. The name has been
changed since it supports both b and c variants of RNG.
2. Added clock and compatible info to the device tree data.
3. Added the entry in the options in the Kconfig for hwrng.

This patch cherry-pick from the below commit, but make little change:
align i.mx6dl with i.mx6q, since TKT238285 should be exit on other chips
although it can't reproduced by SPI-NOR, now there is official workaround
for this bug(a619a00e11a67b00805b9148f004a3c94d54f863). So this patch just
enable dma support on i.mx6sl and i.mx6sx.

IMX6 has been (ab)using the gic_arch_extn to provide
wakeup from suspend, and it makes a lot of sense to convert
this code to use stacked domains instead.
This patch does just this, updating the DT files to actually
reflect what the HW provides.
BIG FAT WARNING: because the DTs were so far lying by not
exposing the fact that the GPC block is actually the first
interrupt controller in the chain, kernels with this patch
applied wont have any suspend-resume facility when booted
with old DTs, and old kernels with updated DTs won't even boot.
