Fix alignment faults seen during play-back of files with specific sampling rates such as 44.1K. This is based on the discussion here: http://www.spinics.net/lists/arm-kernel/msg384647.html
Patch 1 is needed as m32r arch does not define ioremap_wc. Patch 2 adds a resource managed helper function for ioremap_wc which is used in patch 3.
Changes since v1: - Fix the compilation error with m32r due to missing ioremap_wc definition. - Fixed minor indentation issues.
Note: Other architectures either have ioremap_wc defined or are including generic "io.h"/"iomap.h". c6x arch is the only one I am not sure of.
