To support PCIe MSI on 3.14 kernel, the client's host
driver must use the QGIC IRQ number to request/enable
the interrupt while the client's firmware must use
the SPI number to trigger the interrupt. Therefore,
add this logic in PCIe bus driver to support MSI
interrupts on 3.14 kernel.

A user space application is planned to support feature for
synchronized timestamp among debug packets across peripherals.
As part of the feature, it is responsible for providing physical
timer count value to user space. If memory mapped timer is used
in ARM arch, Usersapce can't read the physical timer count directly
with a MRCC ASM instruction. So Kernel traps the instruction and
returns the physical timer count.
