BL1 is used in recovery mode on HiKey. The TBB implementation
on HiKey is in BL2. It means that user need to build ATF BL2
with TBB and ATF BL1 with non-TBB. It's inconvenient.

So include TBB in BL1, too.

This patch adds experimental support for TRUSTED_BOARD_BOOT to the
Hikey. This is adapted from the RPi3 and QEMU implementations.

Since the Hikey starts from BL2 the TRUSTED_BOARD_BOOT ROT begins there
too. When TRUSTED_BOARD_BOOT is defined, the BL1 build is skipped.

See the following example:

make \
 PLAT=hikey \
 BL33=u-boot.bin \
 SCP_BL2=mcuimage.bin \
 TRUSTED_BOARD_BOOT=1 \
 MBEDTLS_DIR=../../mbedtls \
 GENERATE_COT=1 \

Boot memory layout is specific for a platform, but should not be
mixed up with other platform specific attributes. A separate file is
much cleaner and better to compare with other platforms. Take a look
at plat/poplar where it is done the same way.

Moved hikey_def.h to system include folder and moved includes from
hikey_def.h to more general platform_def.h.

Since non-TF ROM is used in HiKey platform (Hisilicon Hi6220 SoC),
replace BL1 by BL2_EL3 in normal boot mode.

When we recovery images in recovery mode, keep to use BL1.

MISRA C-2012 Rule 7.3 violation: lowercase l shall not be used as literal suffixes.

This patch resolves this for the ULL() macro by using ULL suffix instead
of the ull suffix.

These macros are only defined for corresponding image,
and they are undefined for other images. It means that we have
to use ifdef or defined() instead of relying on being 0 by default.

Every CPU has its own debug module and this module is used by JTAG
debugging and coresight tracing. If without enabling it, it's easily to
introduce lockup issue when we enable debugging features.

This patch is to enable CPU debug module when power on CPU; this allows
connecting to all cores through JTAG and used by kernel coresight
driver.

After disconnect Jumper pin 1-2 in J15 header, the signal VBUS_DET is to
be pulled down to low level. This will assert the interrupt signal in
PMIC and trigger IRQ in GIC; the asserted signal from VBUS_DET is level
triggered and kernel reports the warning for unhooked interrupt handling;
and VBUS_DET stays with low level, this triggers IRQ storm in kernel.

This patch is to disable interrupt for VBUS_DET in PMIC, this can
dismiss the verbose log and IRQ storm after kernel booting.

Initialize regulators, pins and eMMC in BL1. Only SRAM could be used in BL1.
So BL2 will be loaded from eMMC into SRAM later.
