[PATCH 2/2] arm64: dts: qcom: sm8150-mtp: drop incorrect amd,imageon

[Krzysztof Kozlowski]

The SM8150 MTP board does not have magically different GPU than the
SM8150, so it cannot use amd,imageon compatible, also pointed by
dtbs_check:

  sm8150-mtp.dtb: gpu at 2c00000: compatible: 'oneOf' conditional failed, one must be fixed:
    ['qcom,adreno-640.1', 'qcom,adreno', 'amd,imageon'] is too long
    'qcom,adreno-640.1' does not match '^qcom,adreno-[0-9a-f]{8}$'
    'qcom,adreno-640.1' does not match '^amd,imageon-200\\.[0-1]$'
    'amd,imageon' was expected

The incorrect amd,imageon compatible was added in commit f30ac26def18
("arm64: dts: qcom: add sm8150 GPU nodes") to the SM8150 and later moved
to the SM8150 MTP board in commit 1642ab96efa4 ("arm64: dts: qcom:
sm8150: Don't start Adreno in headless mode") with an intention to allow
headless mode.  This should be solved via proper driver quirks, not fake
compatibles.

This change depends on previous driver support, unless we do not care
because MTP is a development platform, not a product.
