The power consumption was reported by Paul Staron to be 100uA higher
when an AnalogIn was used previously.
Problem 1 is that 40uA was used by the async ADC clock, which is never
actually used, so it is disabled. Problem 2 is that setting it for high
speed mode increased it by another 60uA while in deepsleep. This
currently seems to me to be possibly a bug in the design, but the
workaround is checking if this is the case before going to deepsleep,
and if yes, disable it. Afterwards it is re-enabled.
See description. Everything HAL wise went into KLXX, with target
specific in subfolders. Only interrupt and spi are in target specific
since they are target specific.
Also you cannot set the uart anymore for 9 or 10 databits (the code
supported it to set it like that, but the actually read/write only did
8-bits)
