USB: io_ti: fix firmware download on big-endian machines

commit 5509076d1b4485ce9fb07705fcbcd2695907ab5b upstream.

During firmware download the device expects memory addresses in
big-endian byte order. As the wIndex parameter which hold the address is
sent in little-endian byte order regardless of host byte order, we need
to use swab16 rather than cpu_to_be16.

Also make sure to handle the struct ti_i2c_desc size parameter which is
returned in little-endian byte order.
