Since we no-longer have any iwmxxt instructions, the iwmmxt-related
attributes can never be set. Consequently, the marvel-f-iwmmxt
scheduler is redundant as none of the pipes are ever used now.
gcc/ChangeLog:
* config/arm/arm.md (core_cycles): Remove iwmmxt attributes.
* config/arm/types.md (autodetect_type): Likewise.
* config/arm/marvell-f-iwmmxt.md: Removed.
* config/arm/t-arm: Remove marvell-f-iwmmxt.md
