pmb/aportgen/linux.py: add different QCDT implementations (MR 1992)

Adds QCDT templates for Spreadtrum and Exynos SoCs
When "pmbootstrap init" is executed, after the boot image analysis,
if the device is QCDT, then the user is asked about the SoC vendor.
Example:
[HH:MM:SS] SoC vendor (spreadtrum/exynos/other) [other]: exynos
After that, the corresponding template is picked.
