Subject: [PATCH 4/6] wifi: rtw89: 8852b: reset IDMEM mode to default value

For different firmware type, it could use different IDMEM mode, so reset
it to default to avoid encountering error during we bisect firmware
version, like

rtw89_8852be 0000:03:00.0: Firmware version 0.29.26.0, cmd version 0, type 5
rtw89_8852be 0000:03:00.0: Firmware version 0.29.26.0, cmd version 0, type 3
rtw89_8852be 0000:03:00.0: fw security fail
rtw89_8852be 0000:03:00.0: download firmware fail
rtw89_8852be 0000:03:00.0: [ERR]fwdl 0x1E0 = 0x62
rtw89_8852be 0000:03:00.0: [ERR]fwdl 0x83F2 = 0x8
rtw89_8852be 0000:03:00.0: [ERR]fw PC = 0xb8931154
rtw89_8852be 0000:03:00.0: [ERR]fw PC = 0xb8931154
rtw89_8852be 0000:03:00.0: [ERR]fw PC = 0xb8931150
rtw89_8852be 0000:03:00.0: [ERR]fw PC = 0xb8931154
