Add timings for RAM codes 4 and 6 and a timing for 528mHz of RAM code 1,

Turned out that WFI doesn't work reliably on Tegra30 as a trigger for
the power-gating, it causes CPU hang under some circumstances like having
memory controller running of PLLP. The TRM doc states that WFI should be
used for the Big-Little "Cluster Switch", while WFE for the power-gating.
Hence let's use the WFE for CPU0 power-gating, like it is done for the
power-gating of a secondary cores. This fixes CPU hang after entering LP2
with memory running off PLLP.

The video decoder driver was tested by time and works absolutely fine.
The reason why it is in staging is because it doesn't provide common V4L
interface yet, this shouldn't stop driver enabling in the defconfig since
our userspace (libvdpau-tegra) provides combined acceleration of decoding
and displaying without use of V4L.

PRCM_PWROFF_GATING_REG has CPU0 at bit 4 on A83T. So without this
patch, instead of gating the CPU0, the whole cluster was power gated,

Without enabling keep-power-in-suspend, we can't wake the device
up using WOL packet, and the log is flooded with these messages
on resume:

sunxi-mmc 1c10000.mmc: send stop command failed
sunxi-mmc 1c10000.mmc: data error, sending stop command
So to make the WiFi really a wakeup-source, we need to keep it powered
during suspend.

The cooling device properties "#cooling-cells" should either be present
for all the CPUs of a cluster or none. If these are present only for a
subset of CPUs of a cluster then things will start falling apart as soon
as the CPUs are brought online in a different order. For example, this
will happen because the operating system looks for such properties in the
CPU node it is trying to bring up, so that it can register a cooling
device.
Add such missing properties.

With commit b5bbe2235361 ("usb: phy: mxs: Disable external charger
detect in mxs_phy_hw_init()") in tree all of the necessary charger
setup is done by the USB PHY driver which covers all of the affected
i.MX6 SoCs.
NOTE: imx_anatop_usb_chrg_detect_disable() was also called for i.MX7D,
but looking at its datasheet it appears to have a different USB PHY IP
block, so executing i.MX6 charger disable configuration seems
unnecessary.

According to Documentation/devicetree/bindings/iio/accel/mma8452.txt,
the correct interrupt-names are "INT1" and "INT2", so fix them
accordingly.
While at it, modify the node to only specify "INT2" since providing
two interrupts is not necessary or useful (the driver will only use
one).
