The helpers to use SPI host 1 and 2 are unused in the kernel
and taking up space and maintenance hours. New systems should
use device tree and not this, so delete the code.

Thanks!

[1/3] spi: s3c64xx: Delete unused boardfile helpers
      commit: f1ba938e4f98941dc2b77795062e49444ec1fee1
[2/3] spi: s3c64xx: Drop custom gpio setup argument
      commit: 3b5529ae7f3578da633e8ae2ec0715a55a248f9f
[3/3] spi: s3c64xx: Convert to use GPIO descriptors
      commit: a45cf3cc72dd9cfde9db8af32cdf9c431f53f9bc

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark
