[PATCH net v2] net: phy: air_en8811h: restore AN8811HB LED GPIO after MCU restart

[Ziyou Xu <xuziyougm@gmail.com>]

Commit 03b4702fc5e3 ("net: phy: air_en8811h: move LED GPIO
configuration to config_init") moved the EN8811H LED GPIO setup from
probe to config_init because an MD32 restart clears the output-enable
bits.

AN8811HB follows the same initialization sequence: an8811hb_probe()
enables GPIO3/4/5, and later config_init() calls restart MD32.

Move the AN8811HB GPIO setup to the end of an8811hb_config_init(),
matching the current EN8811H path.

Changes in v2:
- Drop the EN8811H change, merged independently as commit 03b4702fc5e3
  ("net: phy: air_en8811h: move LED GPIO configuration to config_init").
- Apply the same fix to AN8811HB per Jakub's review.
- Rebase onto netdev/main.

Not tested on AN8811HB hardware.
