Provide is-vendor-board-qcom macro.
`is-vendor-board-qcom` supplants `is-vendor-board-platform` as the latter's
second operand is always `QCOM`. To check that BOARD is a QCOM one, write:
```
ifneq (,$(call is-vendor-board-qcom,BOARD))
```
Using `is-vendor-board-qcom` before its implied operands `TARGET_BOARD_PLATFORM`
and `QCOM_BOARD_PLATFORMS` are set is an error.
