This patch does the following reorganization to psci power management (PM) handler setup for ARM standard platform ports : 1. The mailbox programming required during `plat_setup_psci_ops()` is identical for all ARM platforms. Hence the implementation of this API is now moved to the common `arm_pm.c` file. Each ARM platform now must define the PLAT_ARM_TRUSTED_MAILBOX_BASE macro, which in current platforms is the same as ARM_SHARED_RAM_BASE. 2. The PSCI PM handler callback structure, `plat_psci_ops`, must now be exported via `plat_arm_psci_pm_ops`. This allows the common implementation of `plat_setup_psci_ops()` to return a platform specific `plat_psci_ops`. In the case of CSS platforms, a default weak implementation of the same is provided in `css_pm.c` which can be overridden by each CSS platform. 3. For CSS platforms, the PSCI PM handlers defined in `css_pm.c` are now made library functions and a new header file `css_pm.h` is added to export these generic PM handlers. This allows the platform to reuse the adequate CSS PM handlers and redefine others which need to be customized when overriding the default `plat_arm_psci_pm_ops` in `css_pm.c`.
