The include/linux/remoteproc/pruss.h file was introduced in series [1] as a
public header file for PRU_RPROC driver (drivers/remoteproc/pru_rproc.c)

The second header file include/linux/pruss_driver.h was introduced much earlier
as part of [2] , "soc: ti: pruss: Add a platform driver for PRUSS in TI SoCs".

As far as I can see, seems like pruss_driver.h was added as a public header
file for PRUSS platform driver (drivers/soc/ti/pruss.c)
