staging: gasket: core: switch to relaxed memory-mapped I/O
Use of readl() is deprecated; readl_relaxed() with appropriate memory
barriers is preferred. Switch to relaxed reads and writes for better
performance as well. Memory barriers required for I/O vs. normal
memory access on Apex devices have already been explicitly coded in the
page table routines.
