crypto: arm/ghash-ce - define fpu before fpu registers are referenced
Building ARMv7 with Clang's integrated assembler leads to errors such
as:
arch/arm/crypto/ghash-ce-core.S:34:11: error: register name expected
t3l .req d16
^
Since no FPU has selected yet Clang considers d16 not a valid register.
Moving the FPU directive on-top allows Clang to parse the registers and
allows to successfully build this file with Clang's integrated assembler.
