Add a prefix to the two existing Samsung panel drivers to set a guideline for future patch submissions. Using vendor prefixes consistently should allow a cleaner organization of the tree.

Rather than DRM_PANEL_LD9040 selecting SPI, which then results in an
increase in the probability of Kconf reporting circular dependencies
(we're one "select" away from that right now), make this depend on
SPI instead.  This is akin to having some driver select DRM.

Having some drivers depend on a subsystem, and other drivers select a
subsystem is a recipe for circular dependencies, and there's really no
need for it.
