net: phy: air_en8811h: select LED GPIO pins based on AN8811HB package variant

Browse source

The AN8811HB comes in two package variants, AN8811HBCN and AN8811HBN,
which use different GPIO pins to drive LED outputs. AN8811HBCN uses
GPIOs 0, 1, and 15, while AN8811HBN uses GPIOs 3, 4, and 5. Using a
fixed GPIO assignment causes incorrect LED behavior on one of the
variants.

Read the package variant from the read-only silicon identification bits
in AN8811HB_HWTRAP2 at probe time and store it in priv->is_an8811hbcn.
Add an8811hb_led_gpio_setup() to configure the correct GPIO output pins
and select lines based on the detected variant, and call it from
config_init.
