core: verify size of allocated shared memory

Makes sure that normal world cannot change the size of allocated shared
memory, resulting in a smaller buffer being allocated.

This reintroduces cc6bc5f94210 ("core: verify size of allocated shared
memory") which was lost with Fixes: 2786f1438fc8 ("core: thread:
separate old SMC interface handling"). In addition is the READ_ONCE()
macro is used when reading the returned size from non-secure shared
memory.

Since then we have a separate set of functions to deal with RPC when
communicating with FF-A. A corresponding size check is added for the
FF-A version of thread_rpc_alloc().

core: kernel: pm: refine suspend/resume sequence order

Change PM generic implementation to call handlers for suspend in the
reserve order in which they were registered and to call handlers for
resume in the opposite order, that is the order in which the handlers
where registered.

This change allows to reuse the driver initialization ordering which is
expected to match device drivers dependencies. This change will be even
more useful when using probe support and dependencies resolution.

The change does not affect the 2 PM registration levels: core and drivers.
Core handlers are still suspends after drivers and resumed before
drivers.

core: pm: add a name to registered pm_callback_handle

Adds an argument to register a name (string debug identifier) for
PM handlers registered to PM framework.

Caller can provide a NULL reference or a valid string pointer. When pager
is enabled, the registration ensures the name lies in an unpaged section,
possibly allocating heap for that purpose.
