Currently only board/vendor/$(BOARD)/config.mk is supported, add the additional usecase of having a vendor generic config.mk for adding functionality like platform-specific build targets. Additionally, fix the ifdef to correctly check for $(BOARDDIR) rather than $(BOARD) since that's what is actually used in the include path.

This is a fork of qtestsign[1] with modifications to integrate with the
U-Boot build system. It is pulled from
f3df53a5f0e3 ("Rename "fw" to "mbn"")
New Qualcomm dev boards flash U-Boot to the "uefi" partition, the format
is a standard ELF file with custom program headers containing Qualcomm
signatures, hashes and other metadata. Currently this is accomplished
with qtestsign manually, let's instead import it so we can integrate it
into the build process.
This library will be used by a new mkmbn.py tool to create MBN files
which can be directly flashed to the board.

Adjust the elf class to support creating ELF files from scratch so that mkmbn can build an MBN file from the U-Boot binary image and fix some imports to work correctly in the U-Boot build system. The new tool inspects the DTB embedded in u-boot.bin and uses a lookup table to determine the appropriate configuration based on the root compatible property, effectively encoding the info that was previously kept in documentation.

The qcom_geni driver reads an ELF from storage and configures a set of registers and programs the firmware to the GENI Serial Engine (GENI-SE) wrapper device for the expected functionality. Unlike the GENI-SE wrapper found in MSM SoCs, the IPQ5210's GENI-SE wrapper is pre-configured for one of the functions defined in 'enum geni_se_protocol_type'. Hence, the firmware download is not needed. Only the register configuration part is needed. Earlier, the boot stages before U-Boot would configure the GENI-SE (to access UART/SPI etc). Since for IPQ5210 U-Boot SPL, the previous stage (i.e. boot ROM) doesn't do that modify the driver to do the register configuration part alone without reading an ELF from the storage.
