Device uses heimdall flash method by default, with uppercase
partition name in it's PIT file. This conflicts with flash on update,
because in Linux partitions named in lowercase. To resolve this conflict,
default flash method changed to fastboot. Heimdall still can be used with
`--method` flag: `pmbootstrap flasher --method heimdall-bootimg flash_kernel`
- enable flash on update flag.
- change default flash method to 'fastboot'
U-boot doesn't output bootscript logs, which makes it hard to debug.
Put bootscript to prebootscript section. Preboot is executed before
boot, and u-boot displays it's logs.
With the pmbootstrap change let's change the deviceinfo variable names
to the non-deprecated version.

Device uses mainline kernel. What works:
- boots
- pstore log
- simple framebuffer
- storage including sdcard
* payload mock device tree:
Payload mock device tree is needed to mock device tree,
when we're overriding linux with u-boot in android boot image.
Stock bootloader needs this dtb appended to gzipped u-boot.
Bootscript is a simple hush shell script, dedicated to boot OS.
It may be customized to implement dual boot or to change kernel
command line.
