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.
