Removing rf_type RF_2T4R from driver as it is dead code.
First reason:
The following table is used to configure the phy base band:
u32 Rtl8192PciEPHY_REGArray[PHY_REGArrayLengthPciE] = {0x0,};
A valid array has at least two columns.
Second reason:
According to a list of devices from wiki the seven shown devices do only support
MIMO config: 1x2:2 in phy modes b,g,n. The only rf chip that is used is RTL8256.
Tested with rtl8192e
Transferred this patch over wlan connection of rtl8192e
This patch series requires the patches:
"[PATCH] staging: rtl8192e: Change filename r8192E_hwimg.x to table.x"
"[PATCH] staging: rtl8192e: Remove call_usermodehelper starting RadioPower.sh"
"[PATCH] staging: rtl8192e: Remove function ..dm_check_ac_dc_power calling a script"

Remove empty array Rtl8192PciEPHY_REGArray and the code where it is used
because it is dead code.

Remove conditions for RF_2T4R because hardware that uses RF_2T4R does not
exist.

Hi Dan,
thanks for the review. Here some answers to your questions:
With patch: "[PATCH] staging: rtl8192e: Change filename r8192E_hwimg.x
to table.x" I changed the filename of r8192E_hwimg.c to table.c and
r8192E_hwimg.h to table.h to adapt filenames from
drivers/net/wireless/realtek/rtlwifi rtl8192ee and rtl8192se. Task is
from TODO file.
Thanks for your support.
Bye Philipp
