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.
