dpll: zl3073x: add DPLL channel status fields to zl3073x_chan

Add mon_status and refsel_status fields to struct zl3073x_chan in a
stat group to cache the 'dpll_mon_status' and 'dpll_refsel_status'
registers.

Add zl3073x_chan_lock_state_get(), zl3073x_chan_is_ho_ready(),
zl3073x_chan_refsel_state_get() and zl3073x_chan_refsel_ref_get()
inline helpers for reading cached state, and zl3073x_chan_state_update()
for refreshing both registers from hardware. Call it from
zl3073x_chan_state_fetch() as well so that channel status is
initialized at device startup.

Call zl3073x_dev_chan_states_update() from the periodic work to
keep the cached state up to date and convert
zl3073x_dpll_lock_status_get() and zl3073x_dpll_selected_ref_get()
to use the cached state via the new helpers instead of direct register
reads.
