Rename 'smcc' to 'smccc'

When the source code says 'SMCC' it is talking about the SMC Calling
Convention. The correct acronym is SMCCC. This affects a few definitions
and file names.

Some files have been renamed (smcc.h, smcc_helpers.h and smcc_macros.S)
but the old files have been kept for compatibility, they include the
new ones with an ERROR_DEPRECATED guard.

2. need write 0x76 to cnt_restart to keep watchdog alive when restore

rockchip: Move to MULTI_CONSOLE_API

This patch changes all Rockchip platforms to use the new
MULTI_CONSOLE_API. The platform-specific plat_crash_console
implementations are removed so that the platform can use the ones from
the common platform code instead.

Also change the registers used in plat_crash_print_regs. The existing
use of x16 and x17 has always been illegal, since those registers are
reserved for use by the linker as a temporary scratch registers in
intra-procedure-call veneers and can never be expected to maintain their
values across a function call.

This patch changes all Rockchip platforms to initialize the serial

base address and divisor values if BL31 is run on top of coreboot.
Moving the BL2-to-BL31 parameter parsing as early as possible to ensure
that the console is available for all following code.

Also update the Rockchip platform to use MULTI_CONSOLE_API.

Replace magic numbers in linkerscripts by PAGE_SIZE

When defining different sections in linker scripts it is needed to align
them to multiples of the page size. In most linker scripts this is done
by aligning to the hardcoded value 4096 instead of PAGE_SIZE.

This may be confusing when taking a look at all the codebase, as 4096
is used in some parts that aren't meant to be a multiple of the page
size.
