[PATCH 1/8] rsi: add new device model for 9116

[Siva Rebbagondla]

9116 device id entry is added in both SDIO and USB interfaces.
New enumberation value taken for the device model. Based on the
device model detected run time, few device specific operations
needs to be performed.

adding rsi_dev_model to get device type in run time, as we can use
same driver for 9113 and 9116 except few firmware load changes.

[PATCH 2/8] rsi: move common part of firmware load to separate function

[Siva Rebbagondla]

Till software bootloader ready state, communication with device is common
for 9113 and 9116. Hence moved that part of firmware loading to separate
function rsi_prepare_fw_load(). Also LMAC_VER_OFFSET is different for 9113
and 9116, so renamed existing macro to LMAC_VER_OFFSET_9113

[PATCH 4/8] rsi: change in device init frame sequence for 9116

[Siva Rebbagondla]

Initial frame exchange sequence has been changed for 9116 chip. Getting MAC
address using EEPROM read frame will be once common device configuration is
done and RESET_MAC frame is sending after bootup parameters confirmation is
received, which are different from RS9113 device

[PATCH 8/8] rsi: miscallaneous changes for 9116 and common

[Siva Rebbagondla]

Below changes are done:
* Device 80MHz clock should be disabled for 9116 in 20MHz band.
* Default edca parameters should be used initially before
  connection.
* Default TA aggregation is 3 for 9116.
* Bootup parameters should be loaded first when channel is
  changed.
* 4 byte register writes are possible for 9116.

The cpu_to_le32() was wrong here, it's already contained in the shifting
that happened here ...


Easier to just write that as

 __le32 *usb_reg_buf;

 ...

 usb_reg_buf[0] = cpu_to_le32(value);

however.

This change also seems completely wrong, and we should probably revert
it?
