Subject: [PATCH v8 7/7] wifi: wilc1000: Add WILC3000 support
From: Ajay Singh <ajay.kathat@...rochip.com>
Add support for the WILC3000 chip. The chip is similar to WILC1000,
except that the register layout is slightly different and it does
not support WPA3/SAE.

V2: - Return -EINVAL in wilc_sdio_init() if chip ID is not supported
- Dispose of wilc_chip_type, replace with is_wilc1000()/is_wilc3000()
- Remove wilc3000 DT compatible string handling, match on wilc1000 only,
the device type can be auto-detected based on chipID
V3: - Define and use WILC3000_BOOTROM_STATUS and WILC3000_CORTUS_BOOT_REGISTER_2
V4: - Fix up after dropping wilc_get_chipid() in netdev.c in 2/5
V5: - Advertise WPA3/SAE to userspace only on WILC1000 in wilc_create_wiphy()
V6: - Rebase on next-20240926
V7: - Fix firmware name printing in wilc_wlan_get_firmware() netdev_info()
- Rebase on next-20241003 / wireless-next/main 5a4d42c1688c
with v2 wifi: wilc1000: Keep slot powered on during suspend/resume
V8: Add RB/TB from Alexis
