spi: docs: update info about 'delay_usecs' 
The 'delay_usecs' field is no longer present on the spi_transfer struct.
This change updates the doc to mention the usage of the (relatively) new
'delay' field.

Mauro Carvalho Chehab 9cdd273e29 spi: docs: convert to ReST and add it to the kABI bookset 
While there's one file there with briefily describes the uAPI,
the documentation was written just like most subsystems: focused
on kernel developers. So, add it together with driver-api books.
