Christian Lamparter f6fbc39706 build: define PWM_SUPPORT arch feature flag
As the PWM has its own sub-system in the Linux kernel,
I think it should be handled in the same way as GPIO, RTC, PCI...

This patch introduces a specific feature flag "pwm" and the
"leds-pwm" kernel module as the first customer.

When disabled, all device packages from all selected devices
will be included in all images by default. (Marked as <*>) You will
still be able to manually deselect any/all packages.
When enabled, each device builds it's own image, including only the
profile packages for that device. (Marked as {M}) You will be able
to change a package to included in all images by marking as {*}, but
will not be able to disable a profile package completely.
To get the most use of this setting, you must set in a .config stub
before calling "make defconfig". Selecting TARGET_MULTI_PROFILE and
then manually selecting (via menuconfig for instance) this option
will have pre-defaulted all profile packages to included, making this
option appear to have had no effect.
