patch/misc: rtw88: fix patch rtw88 driver in 6.12.y, remove in 6.18

[EvilOlaf]

Description

In 6.18.y the driver patch was never applied because there was a file name mismatch. Since the driver exists upstream in 6.13+ fixing the mismatch causing the patch to obviously fail against 6.18.y. It was removed.
Slightly different story for 6.12. Also file name mismatch, therefore the driver was never applied. I let LLM do a minor adjustment and more or less a manual patch rewrite by applying and re-extracting the changes while keeping the patch header as it is.
Thanks @MichaIng for pointing this out.

How Has This Been Tested?

• build sunxi legacy 6.12.80
• no build for any 6.18 since in practical terms nothing has changed. patch has never been applied anyway.

📝 Walkthrough

Walkthrough

This patch extends the Realtek rtw88 wireless driver by introducing new chip/platform source files (rtw8812a, rtw8821a, rtw88xxa variants), expanding register definitions via reg.h, exporting core driver functions (rtw_download_firmware, rtw_set_trx_fifo_info), and updating header declarations for power sequencing and firmware handling across multiple driver components.

Changes

Cohort / File(s)	Summary
New Chip Platform Files drivers/net/wireless/realtek/rtw88/rtw8812a*, drivers/net/wireless/realtek/rtw88/rtw8821a*, drivers/net/wireless/realtek/rtw88/rtw88xxa*	New source files added for rtw8812a, rtw8821a, and rtw88xxa chip variants with platform-specific implementations.
