This was done because Risc PC kernels were compiled as ARMv3, which
does not support long multiply instructions used in this file, to work
around the fact that the Risc PC's bus does not handle half-word
accesses. However, Risc PC kernels were changed to compile as ARMv3M
(ARMv3 with long multiply) in commit 8403bcb779a0 ("ARM: 8801/1:
makefile: use ARMv3M mode for RiscPC"), so selecting ARMv4 for this
file is no longer necessary. Drop this unnecessary code.
