[U-Boot] [PATCH v2] ARM: Reintroduce MACH_TYPE_KM_KIRKWOOD for keymile ARM boards

[Valentin Longchamp]

We got dropped from Linux mach-types.h because of a lack of mainline
support and this is needed since the last Linux/u-boot mach-types
synchro.

This patch also defines CONFIG_MACH_TYPE for all keymile boards, as
this is a mandatory CONFIG for ARM boards now. The initialization
of gd->bd->bi_arch_number is removed form km_arm.c, our board file.
