The coreboot framebuffer driver registers a "simple-framebuffer" device
based on the information from the firmware, after checking that it's
compatible with the formats listed in simplefb.h. It was added before
simpledrm, and its Kconfig marked as dependent on the simplefb driver.

The simpledrm driver can also handle "simple-framebuffer" devices and
the coreboot framebuffer works fine with it on a 'Lick' Chromebook.
Allow building the coreboot framebuffer driver with simpledrm as well.
