bus: ti-sysc: PRUSS OCP configuration

Updates OCP master port configuration to enable memory access outside
of the PRU-ICSS subsystem.

This set of changes configures PRUSS_SYSCFG.STANDBY_INIT bit to enable
the OCP master ports during resume sequence and disables the OCP master
ports during suspend sequence (applicable only on SoCs using OCP
interconnect like the OMAP family).
