ath6kl: Lower SDIO pad drive strength for hw2.1.1 board

Without this change, SDIO shuts down due to CRC error during
data communication to the firmware in some of the platform.
for example, scan request issued to the firmware doesn't
return scan completed events and cause the socket interface
to always return -16 (device busy).

SDIO pad drive strength should be reduced for hw2.1.1 board
to avoid such errors.

Oddly enough I have never seen it. But AFAICT the code is correct and
hw is not used uninitalized so add uninitialized_var() to inform that to
the compiler.

ath6kl: handle firmware names more dynamically

Currently ath6kl has just hardcoded paths to each firmware file. Change
this more dynamic by separating the the directory and file name from each
other. That way it's easier to dynamically create full paths to firmware and
code looks better. And now it's possible to remove a function needed by
devicetree code.

While at it add a structure inside struct ath6kl_hw to contain all
firmware names. I deliberately omitted board file support as
those will be handled later.

This is needed for firmware API 3.
