spi_qsd: Add support for new QUPe controller.

The SPI driver is modified to support the new QUPe
controller (version 0x2). The SPI functionality of the
controller is very similar to the previous QUPe
controller (version 0x1). This change addresses
some cleanup along with register address modifications and
flow changes.
