arm64: dts: exynos: add 'chassis-type' property

A new 'chassis-type' root node property has recently been approved for
the device-tree specification.

Add this property for end-user devices (such as laptops,
smartphones and tablets) based on Samsung Exynos ARM64 SoCs.

arm64: dts: exynos: Rename Samsung and Exynos to lowercase

Fix up inconsistent usage of upper and lowercase letters in "Samsung"
and "Exynos" names.

"SAMSUNG" and "EXYNOS" are not abbreviations but regular trademarked
names. Therefore they should be written with lowercase letters starting
with capital letter.

The lowercase "Exynos" name is promoted by its manufacturer Samsung
Electronics Co., Ltd., in advertisement materials and on website.

Although advertisement materials usually use uppercase "SAMSUNG", the
lowercase version is used in all legal aspects (e.g. on Wikipedia and in
privacy/legal statements on
https://www.samsung.com/semiconductor/privacy-global/).

ARM: dts: exynos: Use - instead of @ for DT OPP entries

Compiling the DT file with W=1, DTC warns like follows:

Warning (unit_address_vs_reg): Node /opp_table0/opp@1000000000 has a
unit name, but no reg property

Fix this by replacing '@' with '-' as the OPP nodes will never have a
"reg" property.

arm64: dts: exynos: Add stmfts touchscreen node for TM2 and TM2E

TM2 and TM2E devices are provided with a ST-Microelectronics
Finger Tip S device with small differences:

- screen size
- TM2E uses the stmfts also as a touchkey for "back" and "menu"

In this commit the initial value of the interrupt line is set to
EXYNOS_PIN_PULL_UP as the interrupt is triggered when the line
goes down.

arm64: dts: exynos: Add initial configuration for DISP clocks for TM2/TM2e

Add initial clock configuration for display subsystem for Exynos5433
based TM2/TM2e boards in device tree in order to avoid dependency on the
configuration left by the bootloader. This initial configuration is also
needed to ensure that display subsystem is operational if display power
domain gets turned off before clock controller is probed and the inital
clock configuration left by the bootloader saved.

TM2 and TM2e uses different rate for DISP PLL clock, but for better
maintainability all 'assigned-clocks-*' properties for DISP CMU are
defines in each board dts instead of redefining the rates property.

arm64: dts: exynos: Make TM2 and TM2E independent from each other

Currently TM2E dts includes TM2 but there are some differences
between the two boards and TM2 has some properties that TM2E
doesn't have.

That's why it's important to keep the two dts files independent
and put all the commonalities in a tm2-common.dtsi file.

At the current status the only two differences between the two
dts files (besides the board name) are ldo31 and ldo38.
