CSRatlas7 is next-gen auto SoC from CSR.
It could bring to customers most integrated SoC solution:
- World leading Bluetooth 4.0 and GNSS baseband
- Audio processing, analog CODEC and ADC by DSP
- Analog video input
- SDR accelerators
- CAN bus support by Cortex-M3

This patch breaks Marco SMP support, but Marco project has been dropped.
So it corrects cpu1 jump/flag address for Atlas7 and removes scu related
logic as scu doesn't expose in cortex-a7.

this patch adds UART0 and UART1 as LLUART port, as the new Atlas7
registers layout are different, it also refines some names of old
hard-coded MARCOs and uses CONFIG_DEBUG_UART_PHYS/DEBUG_UART_VIRT
to define different base addresses for multiple ports.

As dts files have been reorganised under vendor subdirs, dtb files
cannot be removed with "make distclean" now. Thus, this patch moves
dtb files under archclean rule and removes unnecessary entries.

Currently Xen Domain0 has special treatment for ACPI SCI interrupt,
that is initialize irq for ACPI SCI at early stage in a special way as:
xen_init_IRQ()
->pci_xen_initial_domain()
->xen_setup_acpi_sci()
Allocate and initialize irq for ACPI SCI
Function xen_setup_acpi_sci() calls acpi_gsi_to_irq() to get an irq
number for ACPI SCI. But unfortunately acpi_gsi_to_irq() depends on
IOAPIC irqdomains through following path
acpi_gsi_to_irq()
->mp_map_gsi_to_irq()
->mp_map_pin_to_irq()
->check IOAPIC irqdomain
For PV domains, it uses Xen event based interrupt manangement and
doesn't make uses of native IOAPIC, so no irqdomains created for IOAPIC.
This causes Xen domain0 fail to install interrupt handler for ACPI SCI
and all ACPI events will be lost. Please refer to:
https://lkml.org/lkml/2014/12/19/178
So the fix is to get rid of special treatment for ACPI SCI, just treat
ACPI SCI as normal GSI interrupt as:
acpi_gsi_to_irq()
->acpi_register_gsi()
->acpi_register_gsi_xen()
->xen_register_gsi()
With above change, there's no need for xen_setup_acpi_sci() anymore.
The above change also works with bare metal kernel too.

Pull pin control fixes from Linus Walleij:
"Here is a (hopefully final) slew of pin control fixes for the v3.19
series. The deadlock fix is kind of serious and tagged for stable,
the rest is business as usual.
- Fix two deadlocks around the pin control mutexes, a long-standing
issue that manifest itself in plug/unplug of pin controllers.
(Tagged for stable.)
- Handle an error path with zero functions in the Qualcomm pin
controller.
- Drop a bogus second GPIO chip added in the Lantiq driver.
- Fix sudden IRQ loss on Rockchip pin controllers.
- Register the GIT tree in MAINTAINERS"
