arm64: dts: qcom: sa8540p-ride: disable pcie2a node
pcie2a and pcie3a both cause interrupt storms to occur. However, when
both are enabled simultaneously, the two combined interrupt storms will
lead to rcu stalls. Red Hat is the only company still using this board
and since we still need pcie3a, just disable pcie2a.
