bcm4375: added firmware patch for version 18.41.117

[0xIO32]

Adds the firmware patch for bcm4375b1 for the version 18.41.117.

Its based on the 18.41.8.9 patch.

Maybe worth mentioning, I needed libnexmon.so for management frame injection. It didn't work through libfakeioctl, but I think the same issue exists on 18.41.8.9.

Nice work on the 18_41_117 port. Working on the CSI side for the same target (4375b1 / 18.41.117 from a Note 10+ Exynos N975F). Already reproduced your monitor-mode build locally for both 18_41_8_9 and 18_41_117 - remapped the 10 RAM-resident addresses in local_wrapper.c via prologue pattern matching across versions. Deltas non-linear, range -0x850 to +0x76B4 - mostly +0x73C4-0x76B4 of forward shift between the two versions plus a couple of functions that actually shrunk (pkt_buf_get_skb / pkt_buf_free_skb -0x850).

For the CSI ucode patch I'm hitting the dual-ucode question. Pattern-matched the bcm43455c0 0x836-0x83B PhyRxStatus_0..5 cluster against 4375b1 ucode1 and ucode2 - zero hits in 0x800-0x8FF (only 7 sparse stores total there, vs 28 stores in bcm43455c0 including the dense block at 0x836). Looks like the Wi-Fi 6 RX header doesn't land in SHM the same way - probably DMA-direct now.

Did anything in your monitor-mode work give hints about where the RX header is materialized in 4375b1, or which of the two ucodes carries the rx_handler that writes it? I'll keep digging either way. Thanks for the base.
