Instead of passing separate args, introduce
struct mlx5_dpll_synce_status to hold the values obtained by
mlx5_dpll_synce_status_get().

Mode supported is currently reported to the user exactly the same, as
the current mode. That's because mode changing is not implemented.
Remove the leftover mode_supported() op and use mode_get() to fill up
the supported mode exposed to user.
One, if even, mode changing is going to be introduced, this could be
very easily taken back. In the meantime, prevent drivers form
implementing this in wrong way (as for example recent netdevsim
implementation attempt intended to do).

When building with -Wincompatible-function-pointer-types-strict, a
warning designed to catch potential kCFI failures at build time rather
than run time due to incorrect function pointer types, there is a
warning due to a mismatch between the type of the mode parameter in
mlx5_dpll_device_mode_get() vs. what the function pointer prototype for
->mode_get() in 'struct dpll_device_ops' expects.
drivers/net/ethernet/mellanox/mlx5/core/dpll.c:141:14: error: incompatible function pointer types initializing 'int (*)(const struct dpll_device *, void *, enum dpll_mode *, struct netlink_ext_ack *)' with an expression of type 'int (const struct dpll_device *, void *, u32 *, struct netlink_ext_ack *)' (aka 'int (const struct dpll_device *, void *, unsigned int *, struct netlink_ext_ack *)') [-Werror,-Wincompatible-function-pointer-types-strict]
141 | .mode_get = mlx5_dpll_device_mode_get,
| ^~~~~~~~~~~~~~~~~~~~~~~~~
1 error generated.
Change the type of the mode parameter in mlx5_dpll_device_mode_get() to
clear up the warning and avoid kCFI failures at run time.

Implement SyncE support using newly introduced DPLL support.
Make sure that each PFs/VFs/SFs probed with appropriate capability
will spawn a dpll auxiliary device and register appropriate dpll device
and pin instances.
