This patch adds cpu node for Exynos4412. Because headsmp.S distinguish
a core by using the combination of cluster id and core id after the
commit 'add support secondary core bootup in big.LITTLE processor', but
when dt node for cpu is not provided, the core ids are assigned from 0
with the cluster id 0. But Exynos4412's cluster id for its 4 cores is
0xa. So this patch is needed for the cores to get the proper mpidr.

This patch make platsmp be available for Exynos5800. No register stores
the number of cores of Exynos5800. SCU in this code is only needed for
that purpose. So any code related SCU is not needed and get the number
of cores statically for Exynos5800.

Use chipid[27:20] bits to identify the EXYNOS family while setting
up the serial port during the uncompression setup. This uses four
additional bits of chipid to identify the EXYNOS family since this
is required for identifying EXYNOS5420 SoC.

This patch adds support secondary core bootup in big.LITTLE processor
for platsmp. Just core id cannot be used for identification, because
there is a pair of the cores which have same core id. Cluster id have
to be included for their identification. This patch makes cpu index
using cluster id and core id for the calculation of their register
address and the identification. But there is a problem to use cluster id
for core index creation. That is, cluster id does not start from 0 in
old processors which do not have more than one cluster. For example,
Exynos4412's cluster id for its 4 core is 0xa. So I makes all cluster id
to 0 when they are bigger than 1. Normally big.LITTLE processor does not
use platsmp. But at this moment, just for the minimal functionality of
big.LITTLE, this patch adds support for it. This patch can be reverted
after another CPU management method is adopted.

The exynos5 SoCs using A15+A7 can boot to A15 or A7. If it boots using
A7, it can't detect right UART physical address only the part number of
CP15. It's possible to solve as checking Cluster ID additionally.

This was caused by commit 5a8da524049c ("ARM: dts: exynos5420: add dsi
node"), which conflicted with d51cad7df871 ("ARM: dts: remove display
power domain for exynos5420").
The DTS addition should never have been merged through the DRM tree in
the first place, and it lacked an ack from the platform maintainer
(who would have known that the disp_pd reference got removed).

Display domain is removed due to instability issues. Explaining
the problem below:
exynos_init_late triggers the pm_genpd_poweroff_unused which powers
off the unused power domains. This call hits before the trigger to
deferred probes.
DRM DP Panel defers the probe due to supply get failure. By the time,
deferred probe is scheduled again, Display Power Domain is powered
off by pm_genpd_poweroff_unused.
FIMD and DP drivers are accessing registers during Probe and Bind
callbacks. If display domain is enabled/disabled around register
accesses, display domain gets unstable and we are getting Power Domain
Disable fail notification. Increasing the Timeout also didn't help.

Currently CLK_FOUT_EPLL was set as one of the parents of AUDSS mux.
As per the user manual, it should be CLK_MAU_EPLL.
The problem surfaced when the bootloader in Peach-pit board set
the EPLL clock as the parent of AUDSS mux. While booting the kernel,
we used to get a system hang during late boot if CLK_MAU_EPLL was
disabled.
