nrf/boards: Add support for pca10059.
Add support for pca10059 with REPL over tinyusb USB CDC. The board also includes a board specific module that will recover UICR->REGOUT0 in case this has been erased. This initial support does not preserve any existing bootloader on the pca10090 in case this was present, and expects to use all available flash on the device.
