Change the way McBSP registers are maintained: store values written to the device in a cache in order to make use of those cached values when convenient. This could help for developing the McBSP context save/restore features, as well as solve the problem of possible register corruption, experienced on OMAP1510 based Amstrad Delta board at least. Series created against linux-omap for-next, commit 82f1d8f22f2c65e70206e40a6f17688bf64a892c. All patches tested on OMAP1510 based Amstrad Delta and compile-tested using omap_3430sdp_defconfig at least.
