ASoC: Fixes for v4.9

The most important fix in here is a change which removes the #error
making the topology API unusable as-is since we have recently discovered
some production uses on Chromebooks so need to acknowledge that what
we've got there now is an ABI.

There's also a very big batch of driver specific fixes here which have
kept on being delayed due to more arriving so the update is another of
these bigger than I would like ones.  There is one especially big one in
there, for the Qualcomm code which fixes simultaneous playback and
capture which was broken during the merge window.  The diff for that is
large because it moves blocks of code to different functions but it's
functionally fairly simple and if it breaks it should have been very
obvious in testing.

+* Aspeed BT (Block Transfer) IPMI interface
+
+The Aspeed SOCs (AST2400 and AST2500) are commonly used as BMCs
+(BaseBoard Management Controllers) and the BT interface can be used to
+perform in-band IPMI communication with their host.
+
+Required properties:
+
+- compatible : should be "aspeed,ast2400-bt-bmc"
+- reg: physical address and size of the registers
+
+Optional properties:
+
+- interrupts: interrupt generated by the BT interface. without an
+  interrupt, the driver will operate in poll mode.
+
+Example:
+
+	ibt@1e789140 {
+		compatible = "aspeed,ast2400-bt-bmc";
+		reg = <0x1e789140 0x18>;
+		interrupts = <8>;
+	};
