csky: Make pfn accessors static inlines
Making virt_to_pfn() a static inline taking a strongly typed
(const void *) makes the contract of a passing a pointer of that
type to the function explicit and exposes any misuse of the
macro virt_to_pfn() acting polymorphic and accepting many types
such as (void *), (unitptr_t) or (unsigned long) as arguments
without warnings.
For symmetry to the same thing with pfn_to_virt().
In order to do this we move the virt_to_phys() and
phys_to_virt() below the definitions of the __pa()
and __va() macros so it compiles. The macro version was also
able to do recursive symbol resolution.
