Dan Handley c5945735a9 Move PSCI global functions out of private header
Move the PSCI global functions out of psci_private.h and into
psci.h to allow the standard service to only depend on psci.h.

Dan Handley 5b827a8fb6 Separate BL functions out of arch.h
Move the BL function prototypes out of arch.h and into the
appropriate header files to allow more efficient header file
inclusion. Create new BL private header files where there is no
sensible existing header file.

Vikram Kanigiri 759ec93b69 Preserve PSCI cpu_suspend 'power_state' parameter.
This patch saves the 'power_state' parameter prior to suspending
a cpu and invalidates it upon its resumption. The 'affinity level'
and 'state id' fields of this parameter can be read using a set of
public and private apis. Validation of power state parameter is
introduced which checks for SBZ bits are zero.
This change also takes care of flushing the parameter from the cache
to main memory. This ensures that it is available after cpu reset
when the caches and mmu are turned off. The earlier support for
saving only the 'affinity level' field of the 'power_state' parameter
has also been reworked.

Andrew Thoelke 0a30cf54af Place assembler functions in separate sections
This extends the --gc-sections behaviour to the many assembler
support functions in the firmware images by placing each function
into its own code section. This is achieved by creating a 'func'
macro used to declare each function label.

Vikram Kanigiri d118f9f864 Add standby state support in PSCI cpu_suspend api
This patch adds support in the generic PSCI implementation to call a
platform specific function to enter a standby state using an example
implementation in ARM FVP port

Vikram Kanigiri 6ba0b6d674 Remove partially qualified asm helper functions
Each ARM Trusted Firmware image should know in which EL it is running
and it should use the corresponding register directly instead of reading
currentEL and knowing which asm register to read/write

Jeenu Viswambharan 64f6ea9be7 Implement ARM Standard Service
This patch implements ARM Standard Service as a runtime service and adds
support for call count, UID and revision information SMCs. The existing
PSCI implementation is subsumed by the Standard Service calls and all
PSCI calls are therefore dispatched by the Standard Service to the PSCI
handler.

At present, PSCI is the only specification under Standard Service. Thus
call count returns the number of PSCI calls implemented. As this is the
initial implementation, a revision number of 0.1 is returned for call
revision.
