The Qualcomm TrustZone interface memory allocator is specific to
Qualcomm firmware. Hence add a dependency on QCOM_TZMEM, to prevent
asking the user about these options when configuring a kernel without
Qualcomm firmware support. Various Qualcomm drivers already select the
main QCOM_SCM gatekeeper symbol, which in turn selects QCOM_TZMEM, so it
is auto-enabled when needed.
While at it, add "Qualcomm" to the one-line summary for the choice
option, to make it clear this is not related to generic TrustZone
support.
