leds: pca955x: Drop platform data and allocate LEDs with the device

struct pca955x_platform_data has been private to this driver since
commit ed1f4b9676a8 ("leds: pca955x: add device tree support"), so
nothing can pass it in through dev_get_platdata() and it only serves
as an intermediate copy of the per-LED type, default state and fwnode.
That copy is a full array of struct pca955x_led, the same runtime
structure that struct pca955x already holds, so the data is stored
twice.

Remove the platform data and parse the child firmware nodes directly
into pca955x->leds[]. Make leds[] a flexible array member so it is
allocated together with struct pca955x. This removes three
allocations and the num_leds sanity check, which could no longer
fail.

struct pca955x_led moves above struct pca955x, as a flexible array
member needs the complete element type.
