Adding this parameter so that it could provide more info when
kernel panic happens. And this has almost no overhead as it only
uses several existing kernel APIs.
The 0x1f is a bitmask for type of info to be dumped, and it means
it will print task/memory/timer/lock/ftrace info when panic happens.

The latest kernel has some issues when unloading dwc3_pci USB driver.
It will cause the kernel panic when unloading dwc3_pci driver in order to
assign USB controller to guest.
So the dwc3_pci won't be loaded.

sometimes, there would be CMA allocate failue when doing cycle rebooting android uos.
as there are different CMA clients, and android trusty need 16M contiguous memory,
32M CMA size may make this failure easy to come out.
This patch is to enlarge the CMA size to 64M, which mitigate the failure.

The guc boot option is refined on the new linux kernel. The boot option of
"i915.enable_guc=0" should be added in order to disable Guc instead of using
"enable_guc_loading/submission". But in order to use the same boot option on
multi kernel, both of them are kept.

HPET reading is much slower than TSC. Using it will hurt SOS performance
a lot, and then the whole system performance.
Remove the strict assignment from cmdline. Then SOS kernel will pickup
TSC as default clocksource.

This reverts commit 5b1c536eee.
For normal case, we connected two HDMI monitors, one for SOS, another for UOS.
Previously UOS has problem when only see one display, it was the bug of
user space driver, then to work around this issue, submit temp patch to let
UOS see two displays.
From latest info, after switch to use github latest user spce driver in stable
branch, such problem was resolved. Then we need revert previous workaround
patch, otherwise, UOS will show on both HDMI1 and HDMI2.
Android HWC has problem when only see one display, then this is
workaround patch to make Android HDMI2 display normal.

After i915.avail_planes_per_pipe(0x0000F) is added to SOS, it will cause
that the pipe B/C is initialized without plane. In such case this pipe
can't be used by UOS, with error: primary plane disabled.
The bootarg is changed so that the pipe B/C on SOS can be initialized with
at least one plane.
