devres: combine function devm_ioremap*
When I tried to use devm_ioremap function and review related
code, I found devm_ioremap_* almost have the similar realize
with each other, which can be combined.
In the former version, I have tried to kill ioremap_cache to
reduce the size of devres, which can not work for ioremap is
not the same as ioremap_nocache in some ARCHs likes ia64.
Therefore, as the suggestion of Christophe, I introduce a help
function __devm_ioremap, let devm_ioremap* inline and call
__devm_ioremap with different devm_ioremap_type.
After apply the patch, the size of devres.o can be reduce from
8216 Bytes to 8052 Bytes in my compile environment.
