Update pwm drivers to use DT_HAS_<compat>_ENABLED Kconfig symbol
to expose the driver and enable it by default based on devicetree.
We remove 'depend on' Kconfig for symbols that would be implied by
the devicetree node existing.

Use this short header style in all Kconfig files:
# <description>
# <copyright>
# <license>
...
Also change all <description>s from
# Kconfig[.extension] - Foo-related options
to just
# Foo-related options
It's clear enough that it's about Kconfig.
The <description> cleanup was done with this command, along with some
manual cleanup (big letter at the start, etc.)
git ls-files '*Kconfig*' | \
xargs sed -i -E '1 s/#\s*Kconfig[\w.-]*\s*-\s*/# /'

Defining a symbol with 'menuconfig' just tells the menuconfig to display
any dependent symbols that immediately follow it in a separate menu.
'menuconfig' has no effect on symbol values.
Making a symbol that doesn't have any dependent symbols after it a
'menuconfig' should be avoided, because then you end up with an empty
menu, which is shown as e.g.
[*] Enable foo ---
This is how it would be shown if there were children but they all
happened to be invisible as well.
With a regular 'config', it turns into
[*] Enable foo
Change all pointless 'menuconfig's to 'config's.
See the section on 'menuconfig' on the Kconfig - Tips and Best Practices
page as well.

- Remove redundant dependencies on the PWM symbol (which show up as
PWM && PWM in the documentation). The 'source's in
drivers/pwm/Kconfig are already within an 'if PWM' block.
- Turn some repeated 'depends on FOO' into 'if FOO' blocks.
- Turn some 'if FOO's that surround a single symbol into
'depends on FOO'.
'if FOO' is equivalent to adding a 'depends on FOO' to each symbol
within the 'if'.

This patch adds basic support for the PWM devices available on the Atmel
SAM family. Beside enabling the driver, everything is selected through
the device tree, including enabling the PWM0 and PWM1 devices. Thus
CONFIG_PWM_0 and CONFIG_PWM_1 are ignored.
