ARM: 6534/1: Make CONFIG_FPE_NWFPE depend on !CONFIG_THUMB2_KERNEL

Browse Source 
Because the nwfpe support is unlikely to be used on new platforms
and requires CONFIG_OABI_COMPAT, which is not generally used with
ARMv7+, we shouldn't expect to build nwfpe support into a Thumb-2
kernel.

At present, nwfpe contains assembly code which isn't Thumb-2
compatible, and for now it doesn't appear useful to port this
code.

All ARMv7-A/R platforms necessarily have VFPv3 hardware floating-
point natively, making emulation unnecessary.

Say Y to include the NWFPE floating point emulator in the kernel.
This is necessary to run most binaries. Linux does not currently
