[PATCH v1 1/1] treewide, spi: Get rid of SPI_MASTER_HALF_DUPLEX

[Andy Shevchenko]

The SPI_MASTER_HALF_DUPLEX is the legacy name of a definition
for a half duplex flag. Since all others had been replaced with
the respective SPI_CONTROLLER prefix get rid of the last one
as well. There is no functional change intended.
