On Juno, the secure privileged invasive debug authentication signal
(SPIDEN) is controlled by board SCC registers, which by default enable
SPIDEN.  Disable secure privileged external debug in release builds by
programming the appropriate Juno SoC registers.

This patch migrates ARM Standard platforms to the refactored TZC driver.

Change-Id: I2a2f60b645f73e14d8f416740c4551cec87cb1fb

Currently, on ARM platforms(ex. Juno) non-secure access to specific
peripheral regions, config registers which are inside and outside CSS
is done in the soc_css_security_setup(). This patch separates the CSS
security setup from the SOC security setup in the css_security_setup().

The CSS security setup involves programming of the internal NIC to
provide access to regions inside the CSS. This is needed only in
Juno, hence Juno implements it in its board files as css_init_nic400().

Move the Juno port from plat/juno to plat/arm/board/juno. Also rename
some of the files so they are consistently prefixed with juno_.
Update the platform makefiles accordingly.
