asm-generic: compat: Cleanup duplicate definitions

There are 7 64bit architectures that support Linux COMPAT mode to
run 32bit applications. A lot of definitions are duplicate:
 - COMPAT_USER_HZ
 - COMPAT_RLIM_INFINITY
 - COMPAT_OFF_T_MAX
 - __compat_uid_t, __compat_uid_t
 - compat_dev_t
 - compat_ipc_pid_t
 - struct compat_flock
 - struct compat_flock64
 - struct compat_statfs
 - struct compat_ipc64_perm, compat_semid64_ds,
	  compat_msqid64_ds, compat_shmid64_ds

Cleanup duplicate definitions and merge them into asm-generic.
