[PATCH] MIPS: io.h: Define `ioremap_cache'

Ralf,

 Please try and push it ASAP, with 4.5 if possible.  This should be an 
obviously correct internal API consistency fix, along the lines of the 
recent `ioremap_uc' addition.  NB, there's a fallback `ioremap_cache' 
implementation in kernel/memremap.c redirecting to plain `ioremap', but I 
think we should simply do the right thing rather than relying on that 
code.

 Thanks,

  Maciej
