David Nadlinger 7c336f7770 kernel/api: Add additional binary libm functions 
Also factored out (f64, f64) -> f64 libm wrappers into
a macro, similar to the unary ones.

pca006132 a374d8a02f runtime/kernel/dma: reduced replay overhead 
We can just flush the cache once when we get the handle, instead of
everytime before replay.

pca006132 ae07c05db4 runtime: optimize for speed and fix deadlock

use semaphore to signal if the channel is available instead of busy
polling the mutex.

pca006132 0ce45b145e kernel: proper type for static shared variables. 
* Changed the KERNEL_CHANNEL_* to Mutex<T> with proper type, remove the
  need for unsafe.
* Exposed a const pointer to KernelImage, with UnsafeCell holding
  the library field for unbind with interior mutability.

pca006132 0310421085 RTIO DMA: Compiled but not working. 
* Cache flush should be done before playback instead when getting the
  handler.
* `csr::rtio_dma::enable_read()` would loop forever, probably bug in the
  gateware.
