[PATCH -next] drivers/base/node.c: make CACHE_ATTR define static DEVICE_ATTR_RO

[Ruiqi Gong]

The Sparse tool reports as follows:

drivers/base/node.c:239:1: warning:
 symbol 'dev_attr_line_size' was not declared. Should it be static?
drivers/base/node.c:240:1: warning:
 symbol 'dev_attr_indexing' was not declared. Should it be static?

These symbols (and several others) are defined by DEVICE_ATTR_RO(name) in
CACHE_ATTR(name, fmt), and all of them are not used outside of node.c. So let's
mark DEVICE_ATTR_RO(name) static to solve these complains from Sparse.
