powerpc: Use generic fallocate compatibility syscall
The powerpc fallocate compat syscall handler is identical to the
generic implementation provided by commit
59c10c52f573f ("riscv:
compat: syscall: Add compat_sys_call_table implementation"), and as
such can be removed in favour of the generic implementation.
A future patch series will replace more architecture-defined syscall
handlers with generic implementations, dependent on introducing generic
implementations that are compatible with powerpc and arm's parameter
reorderings.
