[PR] arch/arm/src/samv7/sam_serial_spi.c: set correct SPI mode during init [nuttx]

["michallenc (via GitHub)" <gi...@apache.org>]

michallenc opened a new pull request, #16465:
URL: https://github.com/apache/nuttx/pull/16465

   ## Summary
   Bitfield `CPHA` has to be set to run SPI in mode 0. This is a default mode, therefore it should be set during the peripheral initialization.
   
   ## Impact
   
   Samv7 only. SPI on USART is now initialized in a correct mode.
   
   ## Testing
   
   Tested against icjx io expander. The mode selection is now correct also according to an oscilloscope (previous behavior had data change on leading edge and sampled on falling edge)
