net/libertas: remove GPIO-CS handling in SPI interface code
This removes the dependency on GPIO framework and lets the SPI host driver handle the chip select. The SPI host driver is required to keep the CS active for the entire message unless cs_change says otherwise. This patch collects the two/three single SPI transfers into a message. Also the delay in read path in case use_dummy_writes are not used is moved into the SPI host driver.
