Use TC instead of TXE
...
Transfer Complete is preferable to TX Empty when using a DMA since we could be
polling the bit between transfers. TXE would be 1 but the DMA would be
transfering another at the same time. TC takes the DMA into account

Temporary fix for mbuf's byte index
...
Each buffer should use its own byte index since the value would otherwise be
overwritten when writing to other buffers

Fix RAM initialisation
...
The reset handler is responsible for loading the variables default values. This
includes variables initialized to 0, although they are handed through bss and
not data

Move DMA config to buffers
...
Control over most parameters is not needed since they cannot change for the
buffer to work as expected. Only the priority should be adjustable

This parameter is necessary for DMA tools to be implemented with minimal flash
usage as it allow the use of a single callback function for all purposes instead
of the need to add separate callback functions

Replace rcc's bitfields with macros
...
Bitfields can use byte acces, which the bus doesn't permit. When that happens,
the bus adds extra bytes to form a word, modifying fields that shouldn't be.
Bitfields can be kept for debug and read, but writes must be done though masks
