There isn't any specific power on/off for UART as such(or any on omap1510?).
But yes we can have all the clk and pm related functions to be grouped under
uart_ops->pm().

I don't think the name would conflict as only our uart instance would be up and
working. Right now this driver is supported and tested only on OMAP2/OMAP3. But
yes, once it's in it can be easily ported on other TI platforms.
I will resend the patch with only OMAP2/OMAP3 support as of now.
