Subject: [PATCH v4 1/6] arch: unify ioremap prototypes and macro aliases
Some archs define the first parameter to ioremap() as unsigned long,
while the balance define it as resource_size_t. Unify on
resource_size_t to enable passing ioremap function pointers. Also, some
archs use function-like macros for defining ioremap aliases, but
asm-generic/iomap.h expects object-like macros, unify on the latter.
