hikey: Disable VBUS_DET interrupt for PMIC

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.

hikey: support BL1

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