Subject: [PATCH] uwe5622: fix compilation with clang on Linux 6.19 (#9314)

In Linux 6.19, net_device->dev_addr is const unsigned char *.
Clang with -Werror,-Wincompatible-pointer-types-discards-qualifiers
rejects passing dev_addr to non-const parameters and memcpy into it.

Fix by:
- Replacing memcpy(dev->dev_addr, ...) with dev_addr_set()
- Using local buffer + ether_addr_copy for sprdwl_set_mac_addr call
  that needs mutable addr (the function modifies it in-place)
- Changing u8 *mac pointer to u8 mac[ETH_ALEN] array in cfg80211.c
  where dev_addr was assigned to a non-const pointer

Relates to #9049
