[Sergei: removed useless #include, sorted #include's, fixed HPB_DMA_TCR_MAX,
fixed formats and removed line breaks in the dev_dbg() calls, rephrased and
added IRQ # to the shdma_request_irq() failure message, added MODULE_AUTHOR(),
removed '__init'/'__exit' annotations from the probe()/remove() methods, removed
'__initdata' annotation from 'hpb_dmae_driver', fixed guard macro name in the
header file, fixed #define ASYNCRSTR_ASRST20, added #define ASYNCRSTR_ASRST24,
added the necessary runtime PM calls to the probe() and remove() methods,
handled errors returned by dma_async_device_register(), beautified comments
and #define's.]
