MIPS: uasm: Add option to export uasm API.

Browse source 
A 'select EXPORT_UASM' in Kconfig will cause the uasm to be exported
for use in modules.  When it is exported, all the uasm data and code
cease to be __init and __initdata.

Also daddiu_bug cannot be __cpuinitdata if uasm is exported.  The
cleanest thing is to just make it normal data.
