ARM: s3cxxxx: Use PWM lookup table

Quoted 9 lines · Thierry Reding

Back when the PWM framework was introduced the concept of PWM lookup tables was added to allow board code to register a table of PWM devices and their association with consumers. The goal is to allow drivers to use a unified method to request PWM devices. At the same time, since no boards were exposing these tables, fallback code was kept in drivers to allow old code to remain functional. In order to get rid of the legacy fallback code, legacy users need to be updated to register PWM lookup tables.

This series converts all s3c24xx and s3c64xx boards that hook up a pwm- backlight device to use the new PWM lookup tables. All patches have been compile-tested, but I don't have access to any of these boards, so I couldn't verify that they really work.

Unfortunately I can't verify them neither. I don't have these boards. In that case I would prefer approach "if it ain't broken, don't touch it"... unless someone tests the patches of course.
