Adds support for FF-A 1.1. Now OP-TEE will need to be able to work with
both version 1.0 and 1.1 depending on the other endpoint. The callee
supplies its implemented version and OP-TEE chooses the highest common
version and returns that. This is done per endpoint so some endpoint may
very well use version 1.0 while another uses version 1.1.

Two data structures, struct ffa_mem_transaction and struct
ffa_partition_info, are affected. Runtime conditionals are used to
select which version to use based on the negotiated FF-A version.

core: define main interrupt controller data from its driver

All but one platforms define CPU core interrupt controller from their
platform main.c source file next to its main interrupt handler.
This change factorize these implementation by moving the definition
of the controller data instance straight in the controller driver
source file. This change makes each controller driver to implement
straight itr_core_handler() function, preventing a extra branch on
interrupt execution. Interrupt controller driver initialization
function now straight calls itr_core_init().

This changes treats case when CFG_CORE_WORKAROUND_ARM_NMFI is enable
to not conflict with core/arch/arm/kernel/thread.c that already
overrides itr_core_handler() weak implementation.

With this change, the main controller initialization function
(gic_init(), gic_init_base_addr(), gic_cpu_init() and hfic_init())
no more gets the controller data as input argument.

As a consequence, definition of struct hfic_data and struct gic_data
moves from their respective driver header file to the respective
driver source file.

As a consequence, gic_dump() no more requires an argument.
