dmaengine: stm32-dmamux: Simplify code and save a few bytes of memory
STM32_DMAMUX_MAX_DMA_REQUESTS is small (i.e. 32) and when the 'dma_inuse'
bitmap is allocated, there is already a check that 'dma_req' is <= this
limit.
So, there is no good reason to dynamically allocate this bitmap. This
just waste some memory and some cycles.
Use DECLARE_BITMAP with the maximum bitmap size instead.
