wifi: rtw89: cleanup firmware elements parsing
When compiling with clang-18, I've noticed the following:
drivers/net/wireless/realtek/rtw89/fw.c:389:28: warning: cast to smaller
integer type 'enum rtw89_fw_type' from 'const void *' [-Wvoid-pointer-to-enum-cast]
389 | enum rtw89_fw_type type = (enum rtw89_fw_type)data;
| ^~~~~~~~~~~~~~~~~~~~~~~~
drivers/net/wireless/realtek/rtw89/fw.c:569:13: warning: cast to smaller
integer type 'enum rtw89_rf_path' from 'const void *' [-Wvoid-pointer-to-enum-cast]
569 | rf_path = (enum rtw89_rf_path)data;
| ^~~~~~~~~~~~~~~~~~~~~~~~
So avoid brutal everything-to-const-void-and-back casts, introduce
'union rtw89_fw_element_arg' to pass parameters to element handler
callbacks, and adjust all of the related bits accordingly. Compile
tested only.
