Changed min-residence to 10ms(was 100 ms) for cpu-sleep-0.
Tried lower values 5ms and 8ms and it worked fine with Debug Off.
But to accommodate PM Debug On case, 10 ms is required. With this
change, low power idle state is into effect more frequently.
Measured boot time with PM debugs On and Off. No change observed
compared to 100ms value.

The patch is adding external pmufw "Platform Management Unit firmware"
to boot.bin image. Boot.bin is a Xilinx format which bootrom is capable
to read and boot the system. pmufw is copied to the header data section
follows by u-boot-spl.bin. pmufw is consumed by PMU unit (Microblaze)
and SPL runs on a53-0.
This is generated command line when PMUFW_INIT_FILE is setup.

This patch corrects the R5 release sequence by adding the
below steps.
1. Flush dcache to ensure that image loaded into memory.
2. Keep R5 reset just to ensure R5 in reset.
3. Disable caches before accessing TCM as with out this
A53 can do speculative and may result in ECC failures
if TCM's are not initialized. So, it is always better
to disable dcaches before accessing TCM and enable back.

This commit is to add config option

mx6sxsabresd can run different kernel versions, such as NXP 4.1 or mainline.
Currently the rootfs location is passed via mmcblk number and the
problem with this approach is that the mmcblk number for the SD
card changes depending on the kernel version.
In order to avoid such issue, use the UUID method to specify the
rootfs location.

imx_set_wdog_powerdown() is always used to disable the power down
enable bit, so remove the boolean parameter of the function.
It is also a bit strange to write a boolean value into registers,
so this new version makes explicit that we are writing 0.
While at it, rename it to imx_wdog_disable_powerdown().
