[U-Boot] [PATCH] spl: Introduce SPL_DM_SPI Kconfig define

[Lukasz Majewski <lukma@denx.de>]

Dear Tom,

> This define indicates if DM_SPI shall be supported in SPL. This allows
> proper operation of DM converted SPI drivers in SPL, which use
> #if !CONFIG_IS_ENABLED(DM_SPI) to also support not yet DM/DTS
> converted boards.

Tom, are there any issues preventing this patch from being applied to
-master?
