For full support of power modes, this patch adds implementation
external GIC on EXYNOS4.
External GIC of Exynos4 cannot support register banking so
several interrupt related code for CPU1 should be different
from that of CPU0.

Since Samsung EXYNOS4210 cannot support register banking in GIC,
so needs to update CPU interface base address.
The 'gic_chip_data' is used for it, this patch moves gic_chip_data
structure declaraton to arch/arm/include/asm/hardware/gic.h to use
it.

IRQ_MCT_L1 is connected directly to GIC in external GIC mapping,
while in internal GIC mapping, it is connected to GIC through
interrupt combiner. Therfore the affinity for mct1 event timer
interrupt should be changed through IRQ_MCT_L1.

Any interrupts based off either of the onboard VICs cannot be resumed
from any more as it seems set_irq_wake() is now checking the error code
returned from the low level handlers and not setting the wake-state on
the interrupt if this fails.
Ensure that we make the interrupts we can resume from available on the
VIC and then do a pre-sleep mask of all the VIC interrupts as the wakeup
is handled by a seperate block.

Patch 2e711c04db
(PM: Remove sysdev suspend, resume and shutdown operations)
deleted sysdev_suspend(), which was being relied on to call
check_wakeup_irqs() in suspend. If check_wakeup_irqs() is not
called, wake interrupts that are pending when suspend is
entered may be lost. It also breaks IRQCHIP_MASK_ON_SUSPEND,
which is handled in check_wakeup_irqs().
This patch adds a call to check_wakeup_irqs() in syscore_suspend(),
similar to what was deleted in sysdev_suspend().

This driver handles the variants pca9530-pca9533, so it chose the name
"pca953x". However, there is a gpio driver which decided on the same
name. As a result, those two can't be loaded at the same time. Add a
subsystem prefix to make the driver name unique. Device matching will not
suffer, because both are I2C drivers which match using a
i2c_device_id-table which is not altered.

For nommu arch it's implemented by vma->vm_start = pfn << PAGE_SHIFT which
is wrong acroding the original meaning of this function. And some driver
developer using remap_pfn_range() with correct parameter will get
unexpected result because vm_start is changed. It should be implementd
like addr = pfn << PAGE_SHIFT but which is meanless on nommu arch, this
