Clang doesn't seem to support 'q' register notation in the clobbered
list, and hence throws the following error:
arm/fpu.c:235:3: error: unknown register name 'q0' in asm
fpu_reg_read(outdata);
^
arm/fpu.c:59:10: note: expanded from macro 'fpu_reg_read'
: "q0", "q1", "q2", "q3", \
^
arm/fpu.c:281:3: error: unknown register name 'q0' in asm
fpu_reg_write(*indata);
^
arm/fpu.c:92:10: note: expanded from macro 'fpu_reg_write'
: "q0", "q1", "q2", "q3", \
^
2 errors generated.
Hence, replace 'q' with 'v' registers for the clobbered list.
