net: ethernet: enc28j60: support half-duplex SPI controllers The current spi_read_buf function fails on SPI host masters which are only half-duplex capable. Splitting the Tx and Rx part solves this issue. Tested on Raspberry Pi (full duplex) and I2SE Duckbill (half duplex). Signed-off-by: Michael Heimpold <mhei@heimpold.de> Signed-off-by: David S.
