Merge patch series "pwm: put symbols into a menu + use if DM_PWM block instead of depends on"

Quentin Schulz <foss+uboot@0leil.net> says:

This improves readability in menuconfig by putting PWM symbols under a
Kconfig menu.

It also groups PWM symbols that depend on DM_PWM together under an if
DM_PWM block so that we don't need to always list the dependency in the
depends on of the symbol.

No intended change in behavior except how it shows in menuconfig.
