[ARM] 3070/2: Add __ioremap_pfn() API
Patch from Deepak Saxena In working on adding 36-bit addressed supersection support to ioremap(), I came to the conclusion that it would be far simpler to do so by just splitting __ioremap() into a main external interface and adding an __ioremap_pfn() function that takes a pfn + offset into the page that __ioremap() can call. This way existing callers of __ioremap() won't have to change their code and 36-bit systems will just call __ioremap_pfn() and we will not have to deal with unsigned long long variables. Note that __ioremap_pfn() should _NOT_ be called directly by drivers but is reserved for use by arch_ioremap() implementations that map 32-bit resource regions into the real 36-bit address and then call this new function.
