683f1ef7d1 Added a 1.8 V LDO for the digital IOs 
This simple LDO will serve as a powersource for the audio codec and
any other IC with 1.8V IOVCC.

5a18f2f31a Fixed wrong pinout on the 3.5 mm jack 
RX signal is on the same pin as PTT on the Kenwood style connector.
This is used by many HT manufacturers, so for example Baofeng programming
cable can be used to connect to the debug UART of LinHT.

Fixes #31

cc714a7ebe Fixed board edge and position of 3.5 mm jack
