spi: bitbang: Add missing MODULE_DESCRIPTION()

The modpost script is not happy

  WARNING: modpost: missing MODULE_DESCRIPTION() in drivers/spi/spi-bitbang.o

because there is a missing module description.

Add it to the module.

While at it, update the terminology in Kconfig section to be in align
with added description along with the code comments.

          With a few GPIO pins, your system can bitbang the SPI protocol.

+         port, etc).  Or, some systems' SPI host controller drivers use
          this code to manage the per-word or per-transfer accesses to the
          hardware shift registers.
