[PATCH] clean up exports in fs/{open,read_write}.c

[Eugene Teo <eugeneteo@kernel.sg>]

Takashi-san fixed sound/isa/wavefront/wavefront_synth.c to use
request_firmware instead of sys_*. Since that is the last driver in the
kernel that uses sys_{read,close}, this patch kills these exports. sys_open
is left exported for sparc64 only.
