netlink: specs: dpll: drop the pin-set attributes nothing implements

Browse source

pin-set advertises top level direction, prio and state, so the
generated policy accepts them and the generated user space API grows
setters for them. dpll_pin_set_from_nlattr() has cases only for
FREQUENCY, PHASE_ADJUST, PARENT_DEVICE, PARENT_PIN, ESYNC_FREQUENCY and
REFERENCE_SYNC - the request succeeds, does nothing and produces no
extack. The three values are only actionable inside the parent-device
nest, where dpll_pin_parent_device_set() handles them next to
DPLL_A_PIN_PARENT_ID, which is what makes them meaningful: a pin can be
registered with more than one device.

Never implemented - "git log -S 'case DPLL_A_PIN_PRIO'" on
dpll_netlink.c comes up empty - the spec has advertised them since
commit 3badff3a25 ("dpll: spec: Add Netlink spec in YAML").

Note that this does change what the kernel accepts: sending one of the
three now fails validation instead of being ignored.
