Void pointers have been used to access linker symbols, by declaring an
extern pointer, then taking the address of it. This limits symbols
values to aligned pointer values. To remove this restriction an
IMPORT_SYM macro has been introduced, which declares it as a char
pointer and casts it to the required type.

Create hikey_bl_common.c to store duplicated initialization
code in BL1 and BL2.
Signed-off-by: Haojian Zhuang <haojian.zhuang@linaro.org>

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.

Since LOAD_IMAGE_V2 is always enabled in HiKey platform. Drop
LOAD_IMAGE v1 to simplify code.

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.
