Add memory barriers to ensure that all translation table writes
have drained into memory, the TLB invalidation is complete,
and translation register writes are committed before enabling
the MMU.

Also ensure the MMU enable takes effect immediately.

These changes are necessary because of commit 8cec598b.

disable_mmu() cannot work as a C function as there is no control
over data accesses generated by the compiler between disabling and
cleaning the data cache. This results in reading stale data from
main memory.

This patch removes the C version of this function in juno code.
An assembly version has been introduced in commit 2f5dcfef.

This is a miscellaneous commit that fixes all build
errors introduced by the rebase of the Juno codebase
on the latest trusted firmware.

 - Make codebase consistent in its use of #include "" syntax
   for user includes and #include <> syntax for system includes.

 - Sort header files alphabetically

 - Use tag names for structure types.
   Replace instances of the former io_handle and io_dev_handle
   types with uintptr_t.

 - Review the .c and .S files for which header files really need
   including and reorder the #include statements alphabetically.

Rename the array "mmap" in plat/juno/aarch64/plat_common.c to
"juno_mmap", to avoid confusion with the array of the same name
in lib/arch/aarch64/xlat_tables.c

Remove the hard coding of all the MMU related registers with 0 and
disable MMU by clearing the M and C bit in SCTLR_ELx.

Also remove use of partially qualified asm helper functions.

In the Juno port, this function returns the first entry of the
frequency modes table from the memory mapped generic timer.

Note, on Juno mailboxes are 16 bytes because any bigger and they would
overlap the memory used for MHU payload data for SCP->AP transfers.
