sconfig: Add a new "SPI" device type

Update sconfig lex and yacc files to add support for a new "SPI" device
type in the devicetree. SPI device takes only parameter i.e. chip select
number for the device on the SPI bus.

Re-generate the shipped files for sconfig using flex 2.6.0 and bison
3.0.4 (make CONFIG_SCONFIG_GENPARSER=1). Clean up local paths that leak
into generated files.
