[PATCH 09/18] locking/atomic: mips: use s64 for atomic64

[Mark Rutland]

As a step towards making the atomic64 API use consistent types treewide,
let's have the mips atomic64 implementation use s64 as the underlying
type for atomic64_t, rather than long or __s64, matching the generated
headers.

As atomic64_read() depends on the generic defintion of atomic64_t, this
still returns long on 64-bit. This will be converted in a subsequent
patch.

Otherwise, there should be no functional change as a result of this
patch.
