thermal/drivers/samsung: Enable TMU by default

The SoC Thermal Management Unit (TMU) is essential for proper operation
of the SoCs. Kernel should not ask users choice of drivers when that
choice is obvious and known to the developers that answer should be
'yes' or 'module'.

Impact of making it default:

1. arm64 defconfig: No changes, already present in defconfig.

2. arm32: No changes, the driver is already selected by MACH_EXYNOS.

3. COMPILE_TEST builds: enable by default for arm32 or arm64 builds,
whenever ARCH_EXYNOS is selected. This has impact on build time and
feels logical, because if one selects ARCH_EXYNOS then probably by
default wants to build test it entirely. Kernels with COMPILE_TEST
are not supposed to be used for booting.

thermal: 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/).

thermal: exynos: Add the dependency of CONFIG_THERMAL_OF instead of CONFIG_OF

for thermal management from devicetree file

thermal: exynos: Add the dependency of CONFIG_THERMAL_OF instead of CONFIG_OF

The exynos thermal driver use the of_thermal_*() API to parse the basic data
for thermal management from devicetree file. So, if CONFIG_EXYNOS_THERMAL is
selected without CONFIG_THERMAL_OF, kernel can build it without any problem.
But, exynos thermal driver is not working with following error log. This patch
add the dependency of CONFIG_THERMAL_OF instead of CONFIG_OF.

dependency will also allow the driver to be enabled on 64-bit SoCs.
