Provide a hint to power controller for DSU cluster power down

By writing 0 to CLUSTERPWRDN DSU register bit 0, we send an
advisory to the power controller that cluster power is not required
when all cores are powered down.

The AArch32 CLUSTERPWRDN register is architecturally mapped to the
AArch64 CLUSTERPWRDN_EL1 register

A single chip platform requires five mmap entries and a corresponding

three additional mmap entries are required to map the shared SRAM and
the IO regions. A corresponding number of additional translation
tables are required as well.

arm_fpga: Remove bogus timer initialisation

The arm_fpga platform code contains an dubious line to initialise some
timer. On closer inspection this turn out to be bogus, as this was only
needed on some special (older) FPGA board, and is actually not needed on
the current model. Also the base address was wrong anyways.

Remove the code entirely.

gic multichip: add support for clayton

GIC-Clayton supports multichip operation mode which allows it to connect
upto 16 other GIC-Clayton instances. GIC-Clayton's multichip programming
and operation remains same as GIC-600 with a minor change in the
SPI_BLOCKS and SPI_BLOCK_MIN shifts to accommodate additional SPI
ranges. So identify if the GIC v4 extension is enabled by the platform
makefile and appropriately select the SPI_BLOCKS and SPI_BLOCK_MIN
shifts.

coreboot: Add memory range parsing

This patch adds code to parse memory range information passed by
coreboot, and a simple helper to test whether a specific address belongs
to a range. This may be useful for coreboot-using platforms that need to
know information about the system's memory layout (e.g. to check whether
an address passed in via SMC targets valid DRAM).

locks: bakery: use is_dcache_enabled() helper

bakery_lock_normal.c uses the raw register accessor, read_sctlr(_el3)
to check whether the dcache is enabled.

Using is_dcache_enabled() is cleaner, and a good abstraction for
the library code like this.

A problem is is_dcache_enabled() is declared in the local header,
lib/xlat_tables_v2/xlat_tables_private.h

I searched for a good place to declare this helper. Moving it to
arch_helpers.h, closed to cache operation helpers, looks good enough
to me.

I also changed the type of 'is_cached' to bool for consistency,
and to avoid MISRA warnings.
