Fix RCC's speed preset not working in release

Since rcc_configure should always be called before anything else, short timing
depends on hard coded loops. These are too fast in release...

Implement bkp's rtc alarm configuration

Rework exti module to use a simpler API
...
The "specific" lines configuration would not work due to index error in
the callback configuration. While fixing the error, simplifying the API
by moving the afio calls to the calling context seemed a cleaner way to
do things

Move rtc control to new BKP module

the backup circuit and thus also aboeys some restrictions access-wise

Fix major reg bitfield issue
...
A while back, macros had to be put in place to avoid letting the
compiler directly use the bitfields. This was necessary because the
compiler used strb instruction which only write bytes. On the AHB bus,
byte writes are transformed into word writes by repeating the byte,
which caused mayhem in the registers. After a lot of research, turns out
the packed attribute stops the compiler from does optimal (word) writes
and isn't needed anyway. Removing them fixes the issue

Rework DMA buffer to work properly
...
DMA buffers now work reliably with USART. The DMA api has changed to make it
more efficient code-size-wise. This may, however, complicate things when
implementating powersaving features

Simplify dma buffers and adjust usart
...
The dma buffer should be services that are used on top of peripherals. As such,
the usart driver should'nt directly use them, this is up to the user. The
multi-buffer has also been simplified since I was not satisfied with the
previous implementation

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
