1ab08e6879 Sansa AMS: updates DMA API
* Adds a callback to be called on end of transfer
* Add a function to disable a channel
* Services the 2 channels if both are active in the isr

45711ac286 Sansa AMS: centralize clock settings in clock-target.h
Reorder system_init() to initialize peripherals not only in bootloader
Use a 65MHz PCLK (and memclk) which will be needed for realtime decoding

d3e783b268 Fix the Sansa AMS SD driver
- Make write_sectors() function fail.
- Disable interrupts while transferring data and do not yield(), so we are sure the FIFO is not overflowed
Note this solution is only temporary since it's not friendly to other threads and confuse kernel tick precision
This will be reverted when we will be using DMA to access the SD card, but for now it permits further development
- PL180: Rename the MMC_* registers into MCI_*, to not make people believe it is a MMC only controller
- Supports non aligned destination buffers when reading
- Correct the timeout units which were lamely copied from ata-sd-pp.c and were in milliseconds (note that the timeouts are disabled now)
- Higher a bit the stack size
- Use the full initialization procedure in the bootloader and the loaded firmware
- Use the CCU_IO register only when a SD slot is present
- Put some panicf() around to catch problems
