If this and other functions aren't really Rome specific they should
probably be renamed to qca_...

The comment isn't quite accurate, the qca_uart_setup_cherokee() calls
existing functions, but is essentially a copy of qca_uart_setup_rome().
The main difference is that the patch version is passed as a parameter
instead of determining it in the uart setup function. There seems to
be no need to pass the version number in, or if you prefer to do it
this way, you could change the Rome code to do this.
The other delta is the filename extension of the rampatch file, which
is .bin for Rome and .tlv for Cherokee. Is there a good reason to use
a different extension? If not just stick to the existing naming
scheme, otherwise you could pass the chip type as a parameter and
chose the extensions based on that.
Thanks
Matthias
