In preparation to enabling -Wimplicit-fallthrough, mark switch
cases where we are expecting to fall through.
This patch fixes the following warnings:
drivers/net/wireless/realtek/rtw88/phy.c: In function ‘rtw_get_channel_group’:
./include/linux/compiler.h:77:22: warning: this statement may fall through [-Wimplicit-fallthrough=]

This patch is part of the ongoing efforts to enable
-Wimplicit-fallthrough.
