ptp: Fix type of mode parameter in ptp_ocp_dpll_mode_get()
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
ptp_ocp_dpll_mode_get() vs. what the function pointer prototype for
->mode_get() in 'struct dpll_device_ops' expects.
drivers/ptp/ptp_ocp.c:4353:14: 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]
4353 | .mode_get = ptp_ocp_dpll_mode_get,
| ^~~~~~~~~~~~~~~~~~~~~
1 error generated.
Change the type of the mode parameter in ptp_ocp_dpll_mode_get() to
clear up the warning and avoid kCFI failures at run time.
