Make a few improvements to the SioSerial struct:
- Have init() return Self. It's more ergonomic to create and initialize
the empty struct in one call.
- Enable FIFO. The GBA has a 4-byte UART FIFO. This makes it less
likely to lose received bytes.
- Derive Clone on SioSerial so it can be split and shared with an
interrupt.
- Derive Debug on SioError so results can be unwrapped.
* Add Serial and GPIO registers and implement embedded_hal traits
Use VolAddress and phantom_fields to populate the SIOCNT, RCNT, and
SIODATA8 registers. Implement embedded_hal serial traits around an empty
SioSerial struct.
Hide serial read and write traits behind a "serial" feature flag
to make embedded-hal and nb dependencies optional.
* UART echo example
Enable the serial feature for this example. Provide a pinout
diagram to assist people with wiring up a USB to UART adapter.
The hello_magic example does not depend on the gba crate, but the crt0
now assumes that the symbol for the interrupt handler which is defined
in it will be present, as interrupts ought to be handled in some
manner. If neither the symbol or the crate are added then the linker
will give an error, but if anything in the gba crate is used also then
the symbol will be brought in, so defining it manually also would
cause a duplicate definition error. In the future something like
cortex-m-rt's `exception!` macro could be used to better document how
to define this symbol (all their examples depend on at least one
symbol from their runtime library, so they don't have this problem).
