[PATCH] ARM: vfp: Remote obsolete fpmx_state field from vfp_hard_struct

[dave.martin@linaro.org (Dave Martin)]

The fpmx_state field was presumably used in the past, when
FSTMX/FLDMX were used to save and resture the VFP state.

This was been deprecated since ARMv6, the context switch code
has been ported to use the double-precision load/store variants
many years ago, and now it appears that nothing in the kernel
references this field any more.
