The arch/arm/mach-exynos4 directory (CONFIG_ARCH_EXYNOS4) has
made for plaforms based on EXYNOS4 SoCs. But since upcoming
Samsung's SoCs such as EXYNOS5 (ARM Cortex A15) can reuse most
codes in current mach-exynos4, one mach-exynos directory will
be used for them.

This patch changes to CONFIG_ARCH_EXYNOS (arch/arm/mach-exynos)
but keeps original CONFIG_ARCH_EXYNOS4 in mach-exynos/Kconfig to
avoid changing in driver side.

The regulator support in the l4f00242t03 is very non-idiomatic.  Rather
than requesting the regulators based on the device name and the supply
names used by the device the driver requires boards to pass system
specific supply names around through platform data.  The driver also
conditionally requests the regulators based on this platform data, adding
unneeded conditional code to the driver.

Fix this by removing the platform data and converting to the standard
idiom, also updating all in tree users of the driver.  As no datasheet
appears to be available for the LCD I'm guessing the names for the
supplies based on the existing users and I've no ability to do anything
more than compile test.

The use of regulator_set_voltage() in the driver is also problematic,
since fixed voltages are required the expectation would be that the
voltages would be fixed in the constraints set by the machines rather than
manually configured by the driver, but is less problematic.

Commit "ARM: gic: add irq_domain support" (b49b6ff) breaks SPARSE_IRQ
on platforms with GIC. When SPARSE_IRQ is enabled, all NR_IRQS or
mach_desc->nr_irqs will be allocated by arch_probe_nr_irqs(). This caused
irq_alloc_descs to allocate irq_descs after the pre-allocated space.

Make irq_alloc_descs search for an exact irq range and assume it has
been pre-allocated on failure. For DT probing dynamic allocation is used.
DT enabled platforms should set their nr_irqs to NR_IRQ_LEGACY and have all
irq_chips allocate their irq_descs with irq_alloc_descs if SPARSE_IRQ is
enabled.

gic_init irq_start param is changed to be signed with negative meaning do
dynamic Linux irq assigment.

The meaning of irq_offset has changed. It now is just the number of skipped
