PRUSS APIs in pruss_driver.h produce lots of compilation errors when
CONFIG_TI_PRUSS is not set.

The errors and warnings,
warning: returning 'void *' from a function with return type 'int' makes
	integer from pointer without a cast [-Wint-conversion]
error: expected identifier or '(' before '{' token

Fix these warnings and errors by fixing the return type of pruss APIs as
well as removing the misplaced semicolon from pruss_cfg_xfr_enable()

Fixes: 0211cc1e4fbb ("soc: ti: pruss: Add helper functions to set GPI mode, MII_RT_event and XFR")
