Modified library to work with Tricore Ifx Qspi driver

[jacobbenlewis]

The Ifx Qspi driver doesn't directly support the manual control of the CS pin. So needed to change some SPI read/write functions to send all at once rather than one byte at a time.

• change spi_transmit_32 to use IfxQspi_SpiMaster_exchange()
• change all the EVE_memReadXX()/WriteXX() functions to call functions using IfxQspi_SpiMaster_exchange()
• change EVE_cmdWrite() to call a function using IfxQspi_SpiMaster_exchange()

3 things still needed external to these mods:

1. spiMasterChannelConfig.base.mode.autoCS = 0; // use manual chip select functions
2. Modify iLLD/TC39B/Tricore/Qspi/SpiMaster/IfxQspi_SpiMaster.c:
   • comment out contents of IfxQspi_SpiMaster_activateSlso()
   • comment out contents of IfxQspi_SpiMaster_deactivateSlso()
3. Need to use the burst commands always, or confirm that spi_transmit() is not used.
