fb: Add shadowfb support ...

For speeding up rendering we need shadow framebuffers. This is currently
implemented in the gui functions. This does not work properly when two
users (splash and fbconsole) use the same framebuffer since in this case
two different shadow framebuffers will be used. This patch implements
shadowfb handling in the fb core directly. With this the fb device gets
a parameter 'shadowfb'. When this is true the fb core will allocate a
shadow fb and provide it to the users.

mtd: nand: mrvl-nand: create initial empty bbt ...

When creating an initial bad blocks table, create it empty. This is
necessary because when the bad block table blocks are not
initialized (all ff) while some partitions are, all the blocks which
have an OOB data not beginning with 0xff 0xff will be marked as bad
blocks in the initial bad blocks scan.

As a consequence, any existing blocks are impossible to erase
anymore. Fix this by fixing the BBT creation flag.

video: simple-panel: mode support depends on I2C and EDID ...

The fixed clocks are registered from devicetree. Therefore the code path is
