5c988510b3 Preserve fdt paddings
Some Motorola devices (Qualcomm kernel with CONFIG_MMI_DEVICE_DTBS
configuration enabled) need 1k of padding to the DTBs to allow for
environment variables to be runtime added by the bootloader.
Those extra paddings will be removed during the process of dtb patch,
devices won’t be able to boot-up and return to fastboot mode immediately
after flashed the flawed boot.img.

c42a51dcbb Add support to patch DTBH DTBs
Apparently, Qualcomm is not the only on creating weird DTB formats,
Samsung also have their own DTBH format for Exynos platforms.

e0927cd763 Add support to patch QCDT
Old Qualcomn devices have their own special QC table of DTB to
store device trees. Since patching fstab is now mandatory on Android 10,
and for older devices all early mount devices have to be included into
the fstab in DTBs, patching QCDT is crucial for rooting Android 10
on legacy devices.

Close #1876 (Thanks for getting me aware of this issue!)
