Cortex-A: Revert back polling of CDBGPWRUPACK and CSYSPWRUPACK
in ahbap_debugport_init() from the Openocd-0.8.0.
Currently implemented timeout based polling fails to connect and less
successfull compared to Openocd-0.8.0. Timeout happens.
Openocd-0.8.0 able to connect all use case of target.
bare-metal, u-boot and kernel.
To the same hardware, Openocd-0.8.0 able to connect,
whereas, the latest version does not able to connect.
