Enable flashing kernel on update + small cleanups for deviceinfo:
* re-sort lines in deviceinfo
* remove console=tty0 from kernel cmdline, so it does not spit out
all kernel logs on the screen. Now during boot you see just
blinking cursor and pmOS logo.
This is needed with the 5.11 kernel. Also adjust the vram & cma sizes
for all msm8974 devices.
The CMA size is 256MB as set in the kernel config.
VRAM is default 16MB although it is set to 192MB with a kernel patch;
but set it manually for all devices to make it possible to remove this
patch in the future - until we have IOMMU working.
Prepare for better device categorization by moving everything to testing
subdir first.
