ice: fix linking when CONFIG_PTP_1588_CLOCK=n
The recent support for DPLL introduced by commit 8a3a565ff210 ("ice: add
admin commands to access cgu configuration") and commit d7999f5ea64b ("ice:
implement dpll interface to control cgu") broke linking the ice driver if
CONFIG_PTP_1588_CLOCK=n:
ld: vmlinux.o: in function `ice_init_feature_support':
(.text+0x8702b8): undefined reference to `ice_is_phy_rclk_present'
ld: (.text+0x8702cd): undefined reference to `ice_is_cgu_present'
ld: (.text+0x8702d9): undefined reference to `ice_is_clock_mux_present_e810t'
ld: vmlinux.o: in function `ice_dpll_init_info_direct_pins':
ice_dpll.c:(.text+0x894167): undefined reference to `ice_cgu_get_pin_freq_supp'
ld: ice_dpll.c:(.text+0x894197): undefined reference to `ice_cgu_get_pin_name'
ld: ice_dpll.c:(.text+0x8941a8): undefined reference to `ice_cgu_get_pin_type'
ld: vmlinux.o: in function `ice_dpll_update_state':
ice_dpll.c:(.text+0x894494): undefined reference to `ice_get_cgu_state'
ld: vmlinux.o: in function `ice_dpll_init':
(.text+0x8953d5): undefined reference to `ice_get_cgu_rclk_pin_info'
The first commit broke things by calling functions in
ice_init_feature_support that are compiled as part of ice_ptp_hw.o,
including:
* ice_is_phy_rclk_present
* ice_is_clock_mux_present_e810t
* ice_is_cgU_present
The second commit continued the break by calling several CGU functions
defined in ice_ptp_hw.c in the DPLL code.
Because the ice_dpll.c file is compiled unconditionally, it will not
link when CONFIG_PTP_1588_CLOCK=n.
It might be possible to break this dependency and expose those functions
without CONFIG_PTP_1588_CLOCK, but that is not clear to me.
For the DPLL case, simply compile ice_dpll.o only when we have
CONFIG_PTP_1588_CLOCK. Add stub no-op implementation of ice_dpll_init() and
ice_dpll_uninit() when CONFIG_PTP_1588_CLOCK=n into ice_dpll.h
The other functions are part of checking the netlist to see if hardware
features are enabled. These checks don't really belong in ice_ptp_hw.c, and
make more sense as part of the ice_common.c file. We already have
ice_is_gps_in_netlist() in ice_common.c which is doing a similar check.
Move the functions into ice_common.c and rename them to have the similar
postfix of "in_netlist()" to be more expressive of what they are actually
checking.
This also makes the ice_find_netlist_node only called from within
ice_common.c, so its safe to mark it static and stop declaring it in the
ice_common.h header as well.
