commit dafbd378a285b44acd8015025227326497cd99d9

PowerPC: Rename __kernel_vdso_get_tbfreq to __kernel_get_tbfreq.
In order for the __kernel_get_tbfreq vDSO call to work the
INTERNAL_VSYSCALL_NCS macro needed to be updated to prevent it from
assuming an integer return type (since the timebase frequency is a 64-bit
value) by specifying the type of the return type as a macro parameter. The
macro then specifically declares the return value as a 'register' (or
implied pair) of the denoted type. The compiler is then informed that this
register (or implied pair) is to be used for the return value.
(cherry picked from commit 471a1672d4d55124de4db8273829f96cc14d424a)
